php Checking if value exists in array of array

Question

I have an array within an array.

$a = array ( 0 => array ( \'value\' => \'America\', ), 1 => array ( \'value\' => \'England\', ), )

PHP doesn't have a native array_search_recursive() function, but you can define one:

function array_search_recursive($needle, $haystack) {
    foreach ($haystack as $value) {
        if (is_array($value) && array_search_recursive($needle, $value)) return true;
        else if ($value == $needle) return true;
    }
    return false;
}

Untested but you get the idea.
