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
