Is there an easy way to delete an element from an array using PHP?

Question

Is there an easy way to delete an element from an array using PHP, such that `foreach ($array)` no longer includes that element? I thought that setting it to `null` would do it, but apparently it does not work.

Answer 1

You can use array_diff() but keep in mind that if there are duplicates of those values it will delete multiple

$array = [0 => "a", 1 => "b", 2 => "c"];

$array = array_diff($array, ["a", "b"]);
