PHP syntax error eludes me
I'm trying to see the error but I can't. Could someone take a look at this and tell me what is wrong.





PHP Code:
  function plot_cam() {
            global $filename,$img,$pause;
            $k = 0;
            Header("Content-type: multipart/x-mixed-replace;boundary=ThisRandomString");
            while ($img[$k]==$filename) {
                print("\n--ThisRandomString\n\n");
                Header("Content-type: text/plain");
                $cam = fopen($filename,"r"); 
                fpassthru($cam);
                 fclose($cam);
                if ($pause) { sleep($pause);} // time between reload, usefull for server usage
                $k++;
                if ($k==count($img)) {
                    echo("\n--ThisRandomString--\n");                    
                }
             }    
    }

Um... if you're getting an error, can you please tell us what it is? Thats an awful lot of code to look through to spot an error, so a specific error and line number would be useful.

Without knowing what the error is, I'll start by suggesting that you put quotation marks around each version number in the IF statements.

Zend Studio rocks.

It works like this:
PHP Code:
/**************************************************************************************

        Browser Detection is provided by Leon Atkinson <leon@clearink.com>

/*------------------------------------------------------------------------------------*/ 
Notice that I removed the slash after the line of stars, which was closing the comment and causing the string to be parsed by PHP.

I would suggest you change it into:
PHP Code:
/**********************************************************************
 *                                                                    *
 * Browser Detection is provided by Leon Atkinson <leon@clearink.com> *
 *                                                                    *
 **********************************************************************/ 
Or if you want to be tha bomb and make it phpdoc compatible (phpdoc rules!) and generally more compact and human readable you could rewrite your code as follows:

PHP Code:
<?php

getBrowserInfo();

/**
 * The plot cam function
 */
function plot_cam()
{
    global $filename,$img,$pause;
    $k = 0;

    Header("Content-type: multipart/x-mixed-replace;boundary=ThisRandomString");

    while ($img[$k]==$filename) 
    {
        print("\n--ThisRandomString\n\n");
        Header("Content-type: text/plain");
        
        $cam = fopen($filename,"r");
        fpassthru($cam);
        fclose($cam);

        if ($pause) { sleep($pause);} // time between reload, usefull for server usage

        $k++;

        if ($k==count($img)) echo("\n--ThisRandomString--\n");
    }
}

/**
 * Browser Detection is provided by Leon Atkinson <leon@clearink.com>
 */
function getBrowserinfo()
{
    /* Get the name the browser calls itself and what version */

    $Browser_Name = strtok($HTTP_USER_AGENT, "/");
    $Browser_Version = strtok(" ");

    /* MSIE lies about its name */
    if(ereg("MSIE", $HTTP_USER_AGENT))    
    {
        $Browser_Name = "MSIE";
        $Browser_Version = strtok("MSIE");
        $Browser_Version = strtok(" ");
        $Browser_Version = strtok(";");
    }

    /* Opera isn't completely honest, either ... */
    /* Modificaton by Chris Mospaw <mospaw@polk-county.com> */
    if(ereg("Opera", $HTTP_USER_AGENT))    
    {
        $Browser_Name = "Opera";
        $Browser_Version = strtok("Opera");
        $Browser_Version = strtok("/");
        $Browser_Version = strtok(";");
    }

    /* try to figure out what platform, windows or mac */
    $Browser_Platform = "unknown";

    if(ereg("Windows",$HTTP_USER_AGENT)
    || ereg("WinNT",$HTTP_USER_AGENT)
    || ereg("Win95",$HTTP_USER_AGENT)) 
        $Browser_Platform = "Windows";

    if(ereg("Mac", $HTTP_USER_AGENT)) 
            $Browser_Platform = "Macintosh";

    if(ereg("X11", $HTTP_USER_AGENT))
        $Browser_Platform = "Unix";

    if(($Browser_Platform == "Windows"))
    {
        if($Browser_Name == "Mozilla")    
        {
            // SERVER PUSH WORK'S ONLY HERE <img src="images/smilies/smile.gif" border="0" alt="">
            if($Browser_Version >= 4.0) plot_cam();
        }
    }
    elseif($Browser_Platform == "Macintosh") 
    {
        if($Browser_Name == "Mozilla") 
        {
            // SERVER PUSH WORK'S ONLY HERE <img src="images/smilies/smile.gif" border="0" alt="">
            if($Browser_Version >= 4.0)  plot_cam();
        }
    }

    elseif($Browser_Platform == "Unix") 
    {
        if($Browser_Name == "Mozilla") 
        {
            // SERVER PUSH WORK'S ONLY HERE <img src="images/smilies/smile.gif" border="0" alt="">
            if($Browser_Version >= 4.0) { plot_cam();}
        }
    }
}
?>
But that is just my style, doesn't have to be yours.
