Not to mention converting all of the array's elements to strings and/or
integers.
Now your array is something completely different from what you wanted.
The solution stated earlier is the most sane one (just using
array_keys() with a search value).
The problem isn't very complicated and doesn't require a complex solution.
This thread is overstating a rudimentary problem (and that's the lack
of understanding PHP arrays).
I was actually alluding to something more disturbing:
<?php
$array = [['foo', 'bar'], ['wibble', 'fnord']];
$array = array_diff($array, [['wibble', 'fnord']]);
print_r($array);
?>
...which makes array_diff and its ilk only useful for scalar elements
(hence the need for the more complicated approach using array_keys(),
which provides a strictness flag).
