PHP按值排序多维数组[重复]

Question

我有一个输入数组，需要按整数顺序 ASC 方向对其进行排序。 如何在 php 7+ 中对该数组进行排序

请帮帮我。

$multiArray = array(
    "description" => array(
            "order" => 3,
            "title" => ''
     ),
    "gallery" => array(
            "order" => 1,
            "title" => ''
    ),
    "params" => array(
            "order" => 2,
            "title" => ''
    ),
    "video" => array(
            "order" => 4,
            "title" => ''
        )
);

你可以试试下面的代码

uasort($multiArray, function ($item, $compare) {
    return $item['order'] <= $compare['order']; 
});
