Search a multidimensional array php [duplicate]

Answer 1

If you only want to find out if a certain value exists and nothing else, this is trivial using recursive iterators:

$found = false;
foreach (new RecursiveIteratorIterator(new RecursiveArrayIterator($array)) as $value) {
    if ($value == 'theValueImLookingFor') {
        $found = true;
        break;
    }
}

It's not much more complex to write this up in a recursive function:

function recursive_in_array($array, $needle) {
    foreach ($array as $value) {
        $isIterable = is_object($value) || is_array($value);
        if ($value == $needle || ($isIterable && recursive_in_array($value, $needle))) {
            return true;
        }
    }
    return false;
}
