Recursive array_search

Question

I have a multi-dimensional array:

$categories = array(
    array(
        \'CategoryID\' => 14308,
        \'CategoryLevel\' => 1,
        \'CategoryNa         


        

Answer 1

function array_search_recursive( $search, $values = array(), $i = 0) {
    $match = false;
    var_dump($i, $search);
    $i++;
    foreach ( $values as $keyState => $val ) {
        var_dump($val == $search, 'expression');
        if ( $val == $search ) {
            return $keyState;
        }
        if ( is_array( $val ) ) {
            $match = array_search_recursive($search, $val, $i);
        }
        if ( $match !== false ) {
            return $keyState;
        }
    }

    return false;
}

echo array_search_recursive($search, $canada)

Edit:

This will return the first key, tested for $canada = array( 'Brazilia' => 'test1', "Alberta" => [ "Airdrie", "Brooks", "Camrose" ], "British Columbia" => [ "Abbotsford" => [ 'a', 'b', 'c' ], "Armstrong", "Castlegar" ], "Manitoba" => [ "Brandon", "Selkirk" ], 'Olanda' => 'test2' ); $search = "Selkirk";
