Hello,
We use PHP 4.3.9. 'register_globals = Off' is set in php.ini. I've heard
using 'global' could cause security problems. Is using $GLOBALS still not
more secure than using the 'global' keyword? How should function foo()
obtain the value of $a?
====
<?php
$a = 'one';
foo();
function foo () {
global $a;
echo "a is $a";
}
?>
===
Thanks in advance,
Bing
