[PHP] in_array for multidimensional arrays

**Eric** · 04-14-2011, 02:42 PM

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

PHP Code:

  function multi_in_array($value, $array)

????: NamePros.com http://www.namepros.com/code/711084-php-in_array-for-multidimensional-arrays.html
{

    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')

????: NamePros.com http://www.namepros.com/showthread.php?t=711084
);

 
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)
