1.2.1062. Searching For Multiple Keys¶
array_search() and array_keys() find keys in an array. array_search() returns the first key that match a value, while array_keys() returns all the keys that match a value.
array_search() and array_keys() both accepts a final parameter to set a strict search or not.
<?php
$array = array(0,1,2,3,4,3);
// $id = 3
$id = array_search($array, 3);
// $ids = [3, 5];
$ids = array_keys($array, 3);
?>
