两链接随机php

Question

我有n个链接，每个链接都有自己的关键字。我想一次在php中显示两个链接。有什么建议吗？这是输入示例：$text[1] = "<a href=https://www.website.ext/post-1/>words 1</a>";$text[2] = "<a href=https://www.website.ext/post-2/>words 2</a>";$text[3] = "<a href=https://www.website.ext/post-3/>words 3</a>";$text[4] = "<a href=https://www.website.ext/post-4/>words 4</a>";$text[5] = "<a href=https://www.website.ext/post-5/>words 5</a>"....输出示例：words 1words 3orwords 5words 2orwords 4words 1

Answer 1

这是可以完成任务的代码示例。您可以使用mt_rand（）函数从数组中选择一个随机索引，然后对其进行回显，也可以使用array_rand（）函数从数组中随机抽取给定数量的元素。

<?php

#example 1

$text = array("a", "b", "c", "d", "e");

$keys = array_rand($text, 2);

echo $text[$keys[0]] . "\n";

echo $text[$keys[1]] . "\n";

#example 2

$text = array("a", "b", "c", "d", "e");

echo $text[mt_rand(0,4)] . "\n";

echo $text[mt_rand(0,4)] . "\n";

?>
