PHP：合并while循环+排序中的两个数组

在Wordpress中，每个WP_查询都会返回POST。在目前的情况下，我有两个职位 每个帖子都包含一些数组。因此，我得到了两个数组，我需要合并它们，以便稍后对它们进行排序。 所以现在如果我打印：

echo "<pre>";
print_r($products_selected);
echo "</pre>";

阵列2：

Array
(

    [0] => Array
        (
            [0] => http://www.page1.com
            [1] => Product 1
        )

    [1] => Array
        (
            [0] => http://www.page2.com
            [1] => Product 2

        )

    [2] => Array
        (
            [0] => http://www.page3.com
            [1] => Product 3
        )

    [3] => Array
        (
            [0] => http://www.page4.com
            [1] => Product 4

        )
    [4] => Array
        (
            [0] => http://www.page5.com
            [1] => Product 5

        )

)

如何合并它们，以便按产品名称排序[1]

例如：

您可以使用array\u merge\u递归$array1、$array2实现这个精确的结果，我将使用array\u merge和usort and。虽然如果你添加一些代码，也许我们可以将你的两个查询合并成一个。。。
