[php] Newbie-friendly PHP "Lessons" - Tilted Forum Project Discussion Community

seretogis · 10-31-2003, 06:22 AM

I've had half a dozen people ask me to teach them PHP in the last few months, so I decided to start working on some easy to understand PHP lessons to help people teach themselves the basics. I only have a couple finished right now, and am always looking for some input, so even if you know PHP already, let me know what you think of these. I am including them in a couple of formats -- text, in the post below, and tarred/gzipped links so you can download them.

Lesson 00 - What is PHP?

Quote:

First, before getting into the specifics of PHP, let's begin with understanding how a web server and HTML works. When you type in a url and hit "enter" you are sending a request to the server to retrieve the document that you have specified. The web server looks at the url that you specify and looks for a matching document, finds it (or doesn't) grabs it, and sends it to you. Your web browser then parses (i.e. looks through) the data and displays it to you. Any change that is made to that HTML file will be viewable by you in the source, and so is considered "client-side." JavaScript is the same way -- the interpretation of the JavaScript is left up to your browser, and so is no work for the server at all, since it just hands the data over to you.

PHP is a bit different. When you request a PHP file, the web server grabs the file and then -- instead of just sending it on to you -- the server itself looks through the file and does the necessary logic (e.g. fetching information from a database, inserting dates, names, and other dynamic data) and then sends the results to your web browser. If you view the source of a PHP file you will only see HTML and JavaScript because all of the work that the PHP/web server does is "server-side." It is done before you ever see a thing.

-- to be continued --

Below is a list of the contents of each lesson file. You should be able to copy/paste the lessons below into a text editor and save the file with a .php extension, and have it work. I will try to keep these as up-to-date as possible.

Lesson 01 - Comments

PHP Code:


			
<?



/*  When you see text with a forward-slash and asterix before it, or two

    forward slashes, that means that it is a 'comment', or just normal text

    which is flagged to be ignored by the PHP engine. The slash-star method

    is best for multiline comments, because you only need to put a slash-star

    when you want the comment to start, and a star-slash when you want it to end. */



//  This is the other form of comments, and in order to use them you

//  need to have a double-slash at the beginning of each line.  This is

//  ideal for small one line comments like variable descriptions.





/*  You will notice that this php file has nothing in it but comments.  So, when run,

    it will do absolutely nothing. */



/*  Now, you may ask, if these are just comments, wtf are <? and ?> doing in here?

    Those are the "php tags".  Before PHP code starts, you put <? and after it ends,

    you put ?>.  It acts similarly to html tags like <table> and </table>. All php (including

    comments) MUST be between the <? and ?> tags.



    Because PHP is a server-side language, all of the stuff between <? and ?> is parsed

    (looked at, executed) by the server before it ever gets to your web browser.  So,

    if you load this up with a web browser and try to "view source" you will see nothing

    at all.  The only part of a PHP program that the web browser will see it the output,

    aka the results of the program. */





/*  ****  Task #1 ***

    Try making your own comment in the space below, including whatever you like.  Try

    out both types of comments /* and // and check to make sure that none of this makes

    it to the web browser!



    Spacing is important in order to retain readability, so try to use four spaces, or

    tabs in order to indent when you need to. */



?>

Lesson 02a - Variables

PHP Code:


			
<?



/*  There are a few different kinds of variables in PHP.  First off, variables are

    the basis of any programming language, and are what gives a program the ability

    to be dynamic.  Variables of all types are denoted by a dollar sign ($) before

    the name.  So, $fruit is a variable named "fruit".  What it contains, however,

    is generally up to you.



    In PHP you don't need to initialize variables -- if you refer to one, it is just..

    "there".  So, you need to be careful about spelling variables consistently and

    not to make typos, because the PHP engine won't really warn you about it and it

    can lead to some frustrating bug-hunting.



    Let's start off with pre-defined variables.  These are variables which PHP itself

    sets every time that it looks through a php file.  These are things like the

    location of the file (02 - variables.php in this case), IP of the person who

    is accessing the file, etc.



    A simple example of setting a variable, is shown below:

*/



    $greeting = "Hello";



/*  You'll notice a few things about this statement which holds true to many things

    about php.  First, the variable is to the left of the = because you are setting

    the value of it, to Hello.  It's easy to understand why if you speak it out-

    loud, "greeting equals Hello".  Secondly, notice how Hello is in quotes?

    This is because it is a string, not a numeric value (like the integer 2, or a

    decimal like 3.14).  All strings need to be surrounded by quotes when you echo

    or manipulate them in any way.  Lastly, notice the semi-colon at the end?  For the

    most part if you make a single statement you need a semi-colon after it to tell PHP

    that you are done.  Think of it as a period.  Loops are an exception to this, but we

    will get to those later.



    Capitalization is very important in PHP.  It is generally a good idea to have all

    variables be entirely lowercase, and only use alphanumeric characters along with

    underscores (_) if necessary.  $greeting is not the same as $Greeting, so it is

    important to remain consistent and watch the typos.



    Now that we have set $greeting, let's do something with it: */



    echo $greeting . " World!<br>";



/*  Whoa, what kind of craziness is this, you ask?  Let's take it one chunk at a time.

    Firstly, "echo" is a command which will print out whatever is to the right of it, to

    the output as long as it exists.  So the first thing that will be echoed is "Hello".

    The period is a concatination operator, which essentially means that it "joins" the

    values to the left and right of it.  So, we are joining the contents of the variable

    greeting with the string " World!" (notice the space!) and printing it out.  The end

    result should print out "Hello World!" to your browser.



    Another way to do this very same thing is to include the variable in the double-quotes

    like below:  */



    echo "$greeting World!<br>";



/*  This will also print out "Hello World!" just as the first example did.  One thing that

    you need to be careful about, however, is what kind of quotes that you use.  Double

    quotes will work fine in the above example, but if you use single quotes (''s) it will

    instead print out "$greeting World!" -- this is because single quotes convert whatever

    is inside them, to a string without parsing any potential variables.



    *** TASK #1 ***



    $SERVER_NAME is a predefined variable which contains the name of the server host (i.e.

    www.seretogis.org) and can be used just like any other variable.



    In the space below, change $greeting to something else (e.g. "Goodbye Cruel") and then

    print out the following, where "www.x.org" is the $SERVER_NAME variable, and Hello is

    your new greeting:

        Hello World, from www.x.org!  */





?>

Lesson 02b - Variables - Arrays

PHP Code:


			
<?



/*  As valuable as singular variables are, arrays are priceless.  An array is basically a

    "stack" of different values, all assigned to different part (indexes) of one variable.

    In order to keep each value separate from the other, they are assigned different numeric

    indexes.  By default, indexes start at 0 and work their way up.  So, the first value that

    you set to an array named $fruit would be referred to as $fruit[0].  I will create an array

    and echo it's contents below:

*/



    $fruit = array( "orange", "apple", "banana" );



    echo $fruit[0] . "&lt;br&gt;"; // will echo "orange" and a newline

    echo $fruit[1] . "&lt;br&gt;"; // will echo "apple" and a newline

    echo $fruit[2] . "&lt;br&gt;"; // will echo "banana" and a newline

    echo $fruit[43] . "&lt;br&gt;"; // will echo nothing but a newline, because index 43 is not set!



/*  An array with numeric (number) indexes is known as a "numerically-indexed array".  You can

    also use words as an index, and that sort of array is referred to as a "hash" by perl veterans.



    Logically, the two types of arrays work the same, but creating a hash and referring to its

    contents works a little differently, as shown below:

*/



    $person = array( "name" =&gt; "Bob",

                     "age" =&gt; 25,

                     "gender" =&gt; "male",

                     "human" =&gt; true );



    echo $person['name'] . "&lt;br&gt;";

    echo $person['age'] . "&lt;br&gt;";

    echo $person['gender'] . "&lt;br&gt;";



/*  As you see in the previous example, both types of arrays can contain a wide variety of data,

    not just strings, but also integers, booleans (true/false), etc.





    *** TASK #1 ***



    In the space below, create a numerically-indexed array called $weekdays and set to it,

    the names of each day of the week ("Monday", "Tuesday", etc).  Then, echo out each one

    with a &lt;br&gt; after it so that they show up in a nice list.  */







?>

Lesson 03a - Loops - if/else

PHP Code:


			
<?



/*  In the previous lesson you learned what variables are, and how to set and display

    them.  Now that you know how to do that, you will need to learn some basic logic

    called "loops" to enable you to do much more powerful things with PHP.



    The first "loop" we will deal with, is if/else.  Let's use the variable $fruit

    and take a look at it's contents.

*/



    $fruit = "apple";



/*  Now, $fruit is a variable so it is something that we can change at any time.  Let's

    add some logic to examine what $fruit is, and output something depending on its value.

*/



    if ( $fruit == "orange" ) {

        echo $fruit . " is a color!";

    }

    else {

        echo $fruit . " is not orange!";

    }



/*  Let's examine this line-by-line:

        1)  if ( $fruit == "orange" ) {

            This does two things.  First, the part between the parenthesis "( )" is a

            comparison.  It means that $fruit must be equal to the string orange in order

            for the next line to be executed.  Be sure to notice that == is used instead

            of =, this is because the two are very different things.  = is used to set the

            value of something, == is used to compare two values.  == is also case-sensitive,

            so orange is not == Orange or ORAnGe.  If you wanted to check if something is

            NOT equal to a value, use != instead of ==.  If you want to see if a variable

            exists at all, you could just type: "if ( $fruit ) {".  And to check to see if

            a variable does not exist?  You guessed it: "if ( ! $fruit ) {"



            Secondly, notice the left brace "{" -- this is important, as it means that it is

            the beginning of code that is to be executed if the comparison is true.  It is not

            necessary if you only plan on executing one line of code, but if you have any more

            than one line and don't use "{" and "}" your script will break.



        2)  echo $fruit . " is a color!";

            This line is what is executed if the comparison in line 1 is true.  The result

            would this printed to the screen: orange is a color!



        3)  }

            This is the counterpart to "{" -- it notifies PHP that the code to be executed is

            over, and that it can move on to other things.



        4)  else {

            This starts what code should be executed if the comparison is false.  I.e. if the

            value of $fruit is not the string orange.



        5)  }

            This concludes the "else" section, and finishes up your if/else loop!



    The else { } section itself is completely optional.  If you ONLY want to do something if

    a variable has a certain value, all other possibilities be damned, you can just use

    lines one through three.

Lesson 03b - Loops - for/foreach

PHP Code:


			
<?



/*  I hope that you remember how to work with arrays, because we will be using them quite

    a bit in this lesson.  If you don't, go through Lesson 02b again to refresh your memory.



    The "for" loop is incredibly useful, and in this lesson you will just learn the most

    common usage of it -- to loop through and print the contents of arrays.  We begin!

*/



    $fruit = array( "apple", "orange", "banana", "lemon", "lime" );



    for ( $x = 0; $x < count( $fruit ); $x++ ) {

        echo $fruit[$x] . "&lt;br&gt;\n";

    }



/*  Let's examine this line-by-line:

        1)  for ( $x = 0; $x < count( $fruit ); $x++ ) {

            This may look a bit confusing, so we will break it up even further -- into the

            three statements which it is composed of:

                $x = 0;

                This first expression is something which is executed only once, at the

                beginning of the loop.  This is a good spot to initialize an increment

                variable (something that we will increment in order to move the loop

                forward).



                $x < count( $fruit );

                Remember comparisons?  This second expression is the comparison for the for

                loop.  count( ) is a function which will, literally, count the number of

                entries in the fruit array.  This way, if you go up and add peach to the

                array, you won't have to change the comparison in your for statement,

                because count( ) will know that you added a value.



                $x++

                The third and final part of the for loop is executed after each interation

                of the loop, EVEN IF THE CONDITION IS NOT TRUE.  This is a good place to

                increment your increment variable, as we do here -- $x++ adds 1 to $x.



        2)  echo $fruit[$x] . "&lt;br&gt;\n";

            This line is what is executed if the comparison in line 1 is true.  Notice how $x

            is between the [ ]?  This is because we want a different value to be printed for

            each iteration.  On the first iteration, it will print out $fruit[0], on the second

            it will print $fruit[1], and so on until the condition is no longer met (i.e. $x

            becomes equal to the number of elements in the fruit array.



        3)  }

            This is the counterpart to "{" -- it notifies PHP that the code to be executed is

            over, and that it can move on to other things.





    Next, the "foreach" loop!  Be aware, a foreach loop works ONLY on arrays!  If you give it

    any other sort of variable, it will vomit all over your new shoes.

Sorry to interupt, but the variable part looks almost like what I'm learning in UNIX right now.

juanvaldes · 11-02-2003, 10:08 PM

Those two types of comments are legal in many many languages so some of this will be old hat for folks with a language or two behind there belts.

Looking good man, bring on the interesting stuff.

TequilaJr · 11-02-2003, 11:14 PM

Cool idea man. I've taken a class in C++, so some of this seems familiar, however, php is foreign to me. An easy to follow guide is just what the doctor ordered.

Is there a way to test php code without having to upload it to a server? Like a program for a virtual enviroment or something

You can run a http server with php on your own system, so you can test from your home system (don't even need to be connected to the net).

Windows:
HTTP Server:
I recommend Apache. Windows 2000 and XP comes with IIS (Microsoft's Web Server), but as I've never used PHP w/ it, I won't talk about it. As gigawatz said, it is a good quick 'n dirty test enviroment. Google for IIS+PHP if you want to try that. You can get the latest version of Win32 Binaries for Apache at:

http://www.apache.org/dyn/closer.cgi...inaries/win32/

I suggest a 2.x version. At the time of this writing, apache_2.0.48-win32-x86-no_ssl.msi would be appropriate for you. Use the .exe version if you don't have the MSI installer (chances are you already do. XP, 2K, and ME comes with it).

Note: If you're using XP, you need to have XP SP1 installed.

PHP:
You can get PHP from:
http://www.php.net/downloads.php

At the time of this writing, the latest stable version is 4.3.3. You can get it here:

http://www.php.net/get/php-4.3.3-ins.../from/a/mirror

Setup:
Once you install those two programs (apache first, then PHP), edit your apache configuration and add this:

ScriptAlias /php/" c:/path-to-php-dir/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php/php.exe"

Then start the Apache service and you should be able to run PHP scripts with no problems.

Other:
There are distributions out there that install everything for you in one big go (and usually come with MySQL, a Database Management System). I've never tried these, so can't verify how good they are. I don't have any links, but I'm guessing you could google for them. Also, below's some links with more indepth insturctions on setting up Apache/PHP/MySQL. Good luck!

Linux
HTTP Server:
Once again, Apache 2.x is recommended. You can get it from:
http://httpd.apache.org/download.cgi

Just chose one of the Unix sources.

PHP:
You can get PHP from: http://www.php.net/downloads.php.

Just choose one of the sources.

Other:
You may want to install MySQL as well. Setting up Apache/PHP on Linux can be a pain, but not too bad. Below are some sites that give you good insturctions on how to do it. These may also go through installing other stuff, like SSL.

http://www.weberdev.com/ViewArticle.php3?ArticleID=378
http://www.devshed.com/Server_Side/P...inglySeamless/
http://www.linuxguruz.com/z.php?id=3...p+mysql+apache

General Links:
The following link(s) will give you setup/install instructions for either Linux or Windows.

http://www.php.net/manual/en/install.apache2.php

OK. That's it. Good Luck. If anyone has anything to add to this or thinks should be changed, just reply to the thread and I'll add it in.

Wow way more information than I expected someone to give. Thank you for taking the time to list those resources for me and anyone else interested.

If you are using XP or 2K apache is not needed, IIS is an option. Due to the fact that this is going to be a personal test system/location IIS will do you just fine. It is provided with the operating system. Then you can locate a php plugin for IIS on php.net. It most likely will be easier to do than the apache + php combination.

However, I am not saying that IIS + php is better, only easier for a quick and dirty test environment.

So I have apache installed, downloaded the php program latch recommended, and put the configs in the right place. Now what? I tried making a small *.php file in notepad and I tried running it and of course it wasn't associated with anything. tried it in internet explorer and that was a no-go as well. What do I do?

The php file needs to go in your root html document directory (which is specified in your Apache config file). Then you point your browser to "http://localhost/yourphpfile.php" and it should run (or give an error if there's a problem with the PHP).

Good luck!

so where is lesson 3?

numist · 11-11-2003, 11:00 PM

hello world, how classic...

Code:

class HelloWorld
{
   public static void main(String args[])
   {
      String greeting = "Hello";
      System.out.println(greeting + " World!");
   }
}

same thing, more junk, result:
boolean truth = (php >= java);

looking forward to more.

[edited to correct logic error, may as well be accurate]

cheerios · 11-12-2003, 12:10 AM

System.out.println(truth)
/*output:
false*/

Sorry for the delay!

Lesson 3a, on the if/else loop, is now available.

Also, I renamed Lesson 2 (variables) to Lesson 2a, and added a Lesson 2b which deals with arrays.

Thanks for all the help. It's a little basic, but that's exactly what the doctor ordered. Still, I wouldn't mind a few more challenging tasks.

Great presentation too.

seretogis Huggles, sir? Location: Seattle	[php] Newbie-friendly PHP "Lessons" I've had half a dozen people ask me to teach them PHP in the last few months, so I decided to start working on some easy to understand PHP lessons to help people teach themselves the basics.

I am including them in a couple of formats -- text, in the post below, and tarred/gzipped links so you can download them.
