search a php array for partial string match

Question

I have an array and I\'d like to search for the string \'green\'. So in this case it should return the $arr[2]

$arr = array(0 =>         


        

Answer 1

PHP 5.3+

array_walk($arr, function($item, $key) {
    if(strpos($item, 'green') !== false) {
        echo 'Found in: ' . $item . ', with key: ' . $key;
    }
});
