Php 随机选择已定义变量的集合

我正努力做到以下几点：

定义多组变量

使用PHP随机选择一个集合

在整个页面中从所选集合回显数据

下面是带有虚拟变量和数据的逻辑示例：

---定义每个集合---

SET 1 {
title1 = Sample School
text1 = School is great
link1 = school-page.php
}

SET 2 {
title2 = Sample Business
text2 = Business is great
link2 = biz-page.php
}

SET 3 {
title3 = Sample Organization
text2 = Organization is great
link3 = org-page.php
}

<h1><?php echo $title(from selected set) ?></h2>
<p><?php echo $text(from selected set) ?></p>
<div>Visit page <a href="<?php echo $link(from selected set) ?>">here</a></div>

——页面内所选集合的输出变量---

SET 1 {
title1 = Sample School
text1 = School is great
link1 = school-page.php
}

SET 2 {
title2 = Sample Business
text2 = Business is great
link2 = biz-page.php
}

SET 3 {
title3 = Sample Organization
text2 = Organization is great
link3 = org-page.php
}

<h1><?php echo $title(from selected set) ?></h2>
<p><?php echo $text(from selected set) ?></p>
<div>Visit page <a href="<?php echo $link(from selected set) ?>">here</a></div>
