PHP page random jump method

php page random jump method

1. First use array to store all urls in the array;

2. Then use array_rand to randomly obtain an array subscript;

3. Finally, use the header combined with the randomly obtained URL to jump to the page.

The code is as follows:

<?php
$arr = array(
	&#39;https://www.baidu.com&#39;,
	&#39;https://cn.bing.com/&#39;,
	&#39;http://google.com/&#39;
);
$key = array_rand($arr, 1);
//输出随机内容
// echo $arr[$key];
header(&#39;Location: &#39; . $arr[$key]);
exit;

Note:

● There cannot be any output before the header is executed

● There cannot be a space between location and:

● The php code after the header will still be executed, so you need to pay attention to using exit

Note: During browser testing, due to browser cache, it is not possible to jump to different addresses every time. Use during testing. http://localhost/test.php?id=1, and constantly changing the value of the id to change the url can solve the problem of invisible effects caused by browser caching.
