Disclaimer: I'm not a php guru, but I use it so maybe I can help a bit.

First, I'm wondering if your use of $text globally might have something 
to do with it with the focus changing on global variables in php4 for 
security purposes. 
(http://www.php.net/manual/en/migration4.variables.php)

Another thought that crossed my mind was that the the print statement 
might need to be quoted thusly:
	print "Compared...";

One other thought, and I'll shut up.  

for($i=1; $i<5; $i++ )
    {
     if( $text[$i]==$id )
      print( 'Compared...' );
      return true;
    }
    return false;

Is there something causing this evaluation always to return false due to 
type or whatever?

Hope this helps,
Dustin
