如何从数组中检索随机值

Question

的print_r($行); 结果如下:

Array
(
    [0] => Array
        (
            [bg_image] => uploads/2013/06/Home_background1.jpg
        )

    [1] => Array
        (
            [bg_image] => uploads/2013/06/Home_background2.jpg
        )

    [2] => Array
        (
            [bg_image] => uploads/2013/06/Home_background3.jpg
        )

)

我正在寻求帮助的是随机选择上面的一个值.我对php很新,很抱歉,如果这是一个基本问题.

Answer 1

echo $rows[array_rand($rows)]['bg_image'];
