I'm trying to unset a key in all objects in an array of objects (basically removing any passwords), doing this:
foreach ( $data['users'] as $user) {
unset($user['password']);
}
But it seems it doesn't effect the 'original' data ... how do I do this by reference (or whatever it takes to make this work as 'expected' – by which I mean, the key is removed from all objects in the original array)?
You can pass the $user as reference like this :
// check this --------------v
foreach ( $data['users'] as &$user) {
unset($user['password']);
}
Try:
foreach ( $data['users'] as $key => $user) {
unset($data['users'][$key]['password']);
}
Or
foreach ( $data['users'] as &$user) {
unset($user['password']);
}
My suggestion:
array_walk($data['users'], function(&$a) {unset($a['password']);});
foreach is faster or slower than array_walk. Maybe with a small array the difference is negligible, so the problem doesn't exist. Usually, I like nonconformist solutions, in order to learn something more.
