您可以像这样制作自己的排序功能。

它根据“标题”键的值进行排序。

$array = array(
    array("title" => "2015-05-20",
        "schedule" => "WEEKENDS"
    ),
    array("title" => "2015-05-16",
        "schedule" => "WEEKENDS"
    )
);

function sortByTitle($a, $b) {
    return $a['title'] - $b['title'];
}

usort($array , 'sortByTitle');

print_r($array);

返回：

Array
(
    [0] => Array
        (
            [title] => 2015-05-16
            [schedule] => WEEKENDS
        )

    [1] => Array
        (
            [title] => 2015-05-20
            [schedule] => WEEKENDS
        )

)
