php - remove element from array based on its value?

Question

i've got a regular array with keys and values.

is there a simple way to remove the array element based on its value or do i have to foreach-loop it through and check every value to remove it?

Answer 1

array_diff:

$array = array('a','b','c');
$array_to_remove = array('a');

$final_array = array_diff($array,$array_to_remove);
// array('b','c');
