php 随机

One way to add a random quote to your website is to use the PHP **switch ()** statement. The switch statement compares one variable with many values and executes one piece of code depending on the value it equals. This allows you to prepare a list of quotations and then use the [**rand ()**][rand] function to select a number randomly that corresponds to one of the quotations.

向您的网站添加随机报价的一种方法是使用PHP **switch()**语句。 switch语句将一个变量与多个值进行比较，并根据它等于的值执行一段代码。 这使您可以准备一个报价单列表，然后使用[**rand()**][rand]函数随机选择一个与报价单相对应的数字。

## 使用开关显示随机报价 **(** Using Switch to Display Random Quotes **)** ##

This example code demonstrates how to use switch () to display a random quote on your website. Each of the sample quotes is set to run when its number is chosen. By [using rand () to choose a random number][rand], one of the quotes is displayed at random. This example accommodates only six quotations, hence the rand (1,6) entry.

此示例代码演示了如何使用switch()在您的网站上显示随机报价。 选择每个样本报价时，将其编号设置为运行。 通过[使用rand()选择一个随机数][rand] ，引号之一会随机显示。 本示例仅容纳六个引号，因此是rand(1,6)条目。

To add more quotes, you change the rand () function to allow for higher numbers and then add in their corresponding cases in the code.

要添加更多的引号，可以更改rand()函数以允许使用更大的数字，然后在代码中添加其相应的大小写。

If you want to include a random quote on your PHP web page, use [include ()][include] to pull the quote from this file, like this:

如果要在PHP网页上包含随机引号，请使用[include()][include]从此文件中提取引号，如下所示：
