Previous Comments: ------------------------------------------------------------------------ [2013-09-11 17:45:31] anon at anon dot anon echo array_key_exists('b', get_defined_vars()) ? "exists" : "doesn't exist"; ------------------------------------------------------------------------ [2013-09-11 12:34:01] kozak at eurosat dot cz Description: ------------ At the moment isset call return true only when variable is set and it is not null. But there is no way (or I do not find it so far), how to just test variable for existance. So it will be perfect if there will be some other call (for eg: exist) or some parametr how to get this behaviour More in example. Test script: --------------- $a = null; $testOnlyExistence = true; echo isset($b); // prints false; echo isset($a); // prints false; echo isset($a, $testOnlyExistence); // prints true; echo isset($b, $testOnlyExistence); // prints false; // or echo exist($a); // prints true; echo exist($b); // prints false; ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65652&edit=1
