有没有简单的方法来获得关联数组的最高数值？

$array = array(
    0 => array(
        'key1' => '123',
        'key2' => 'values we',
        'key3' => 'do not',
        'key4' => 'care about'
    ),
    1 => array(
        'key1' => '124',
        'key2' => 'values we',
        'key3' => 'do not',
        'key4' => 'care about'
    ),
    2 => array(
        'key1' => '125',
        'key2' => 'values we',
        'key3' => 'do not',
        'key4' => 'care about'
    )
);

AwesomeFunction($array, 'key1'); // returns 2 ($array key)

请善意,因为这个问题是用手机写的.谢谢.
