PHP unsetting all variables

Recommended Posts

$keys = array();

foreach($GLOBALS as $k => $v){
	$keys[] = $k;
}

for($t=1;$keys[$t];$t++){
	unset($$keys[$t]);
}
unset($k); unset($v); unset($t);

 

Yup - un-fucking-set.

 

Hopefully Google spiders this and makes it the top result, because I spent forever looking and couldn't find this - had to figure it our myself =/

 

And in case your wonder why you'd ever need this - I'm using it for a template system, to wipe out all of the variables defined before the templates index file gets included.

I can write that code in two lines ...

 

foreach (array_keys($GLOBALS) as $k) unset($$k);
unset($k);

 

of course, you realize that $GLOBALS is now gone, and you can't really get it back. And so is $_GET, $_POST, $_SERVER, etc., etc., ... Hell, I'm not really sure I'm still here!
