Re: make global variables accessible to functions?

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 That way is secure and has nothing to do with register_globals ;)

What you can do too is this: <?php function foo($a) { echo "a is $a"; } ?>
