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?

You can remove the element at any index by using the splice method. If you have an array named arr it can be used in this way to remove an element at any index: arr. splice(n, 1) , with n being the index of the element to remove.
How to remove an element at a specific position or index from an array in JavaScript? To remove elements or items from any position in an array, you can use the splice() array method in JavaScript. Consider this array of numbers, // number array const numArr = [23, 45, 67, 89];
The splice() function changes the contents of an array by removing existing elements and/or adding new elements. In splice the second argument is the number of elements to remove. splice modifies the array in place and returns a new array containing the elements that have been removed.
array_diff:
$array = array('a','b','c');
$array_to_remove = array('a');
$final_array = array_diff($array,$array_to_remove);
// array('b','c');

PHP 5.3 example to remove "foo" from array $a:
<?php
$a = array("foo", "bar");
$a = array_filter($a, function($v) { return $v != "foo"; });
?>
The second parameter can be any kind of PHP callback (e.g., name of function as a string). You could also use a function generating function if the search value is not constant.
