$foo++ is 'postfix', ++$foo is 'prefix' This means that the addition of 1 occurs AFTER (hence post) the expression's value is returned, not before. In other words, it's equivalent to this: print $foo; $foo = $foo + 1; not this: $foo = $foo + 1; print $foo; -- Daniel Grace -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
