I've got an array, which I want to filter by an external variable. The situation is as follows:
$id = '1';
var_dump($id);
$foo = array_filter($bar, function($obj){
if (isset($obj->foo)) {
var_dump($id);
if ($obj->foo == $id) return true;
}
return false;
});
The first var_dump
returns the ID (which is dynamically set ofcourse), however, the second var_dump
returns NULL.
Can anyone tell me why, and how to solve it?
