如何使用PHP从目录中获取随机图像 [英] How to get random image from directory using PHP

问题描述

我有一个名为images/tips的目录.

I have one directory called images/tips.

现在在该目录中，我可以更改很多图像.

Now in that directory I have many images which can change.

我希望PHP脚本读取目录，查找图像，然后从那些图像中选择一个随机图像.

I want the PHP script to read the directory, to find the images, and out of those images found to pick a random image.

关于如何执行此操作的任何想法?

Any idea on how to do this?

推荐答案

$imagesDir = 'images/tips/';

$images = glob($imagesDir . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

$randomImage = $images[array_rand($images)]; // See comments

您可以向array_rand()发送第二个参数以获取大于1的值.

You can send a 2nd argument to array_rand() to get more than 1.
