So how is this function of random celebrity quotes implemented?

It's actually very simple. You only need a stringvariable, which contains all the famous quotes to be displayed randomly, and then use explode The function is decomposed into an array, and then a rand random number is used to generate a value and a certain sentence in the array is output.

Go directly to the code:
says.php

The code is as follows:

<?php 
function random_str () { 
$poems="人生的价值，并不是用时间，而是用深度去衡量的。－－ 列夫·托尔斯泰

$poems=explode("\n",$poems); 
return $poems[rand(0,count($poems)-1)];
