note 69950 added to function.isset

The unexpected results of isset has been really frustrating to me. Hence, it doesn't work how you'd think it would, (as documented) a var currently in the scope with a null value will return false. Heres a quick solution, perhaps there are better ways of going about this, but heres my solution... function is_set( $varname, $parent=null ) { if ( !is_array( $parent ) && !is_object($parent) ) { $parent = $GLOBALS; } return array_key_exists( $varname, $parent ); } Hence, $varname should be a mixed value of var's to check for, and $parent can be an array or object, which will default to the GLOBAL scope. See the documentation of array_key_exists for further information. This will allow to check if a var is in the current scope, object, or array... Whether it's a null, false, true, or any value. It depends on ARRAY_KEY_EXISTS for it's functionality which also works with Objects.
