You could do something like this...

    foreach (get_defined_vars() as $var => $val) {
        unset($$var, $var, $val);
    }

But this would be completely unnecessary and redundant.  At the end of a function or on return, all variables and internal reference counts within the scope of the function are essentially cleaned up or removed automatically, and garbage collection takes care of it from there (see: http://us.php.net/manual/en/features.gc.refcounting-basics.php). What specifically are you trying to accomplish or what problem are you facing?

Hello All,

Is there a way to unset all variables within a function?

Or has this got to be done on an individual basis?
