[PHP] In_array for multidimensional arrays

[Eric]

Simple function to check if a value exists in a multidimensional array.

function multi_in_array($value, $array)
{
	foreach ($array AS $item)
	{
		if (!is_array($item))
		{
			if ($item == $value)
			{
				return true;
			}
			continue;
		}

		if (in_array($value, $item))
		{
			return true;
		}
		else if (multi_in_array($value, $item))
		{
			return true;
		}
	}
	return false;
}

// Example
$array = array(
	'Test' => array('test1', 'test2', 'test3'),
	'Hmm'  => array('hmm1', 'hmm2', 'hmm3')
);

var_dump(multi_in_array('test2', $array));
var_dump(multi_in_array('hmm1', $array));
var_dump(multi_in_array('alsdkfj', $array));

// bool(true) bool(true) bool(false)
