The examples are as follows:

<!doctype html>
<meta http-equiv="content-type" content="text/html" charset="utf-8"/>
switch语句，switch语句用于根据多个不同条件执行不同动作。<br/>
如果你希望有选择地执行若干代码块之一，还请使用switch语句。
<br/>
语法结构如下：
<pre class="brush:php;toolbar:false">
switch(n)
{
case label1:
  如n=label1，此处代码将执行；
  break;
case label2:
  如n=label2，此处代码将执行；
  break;
case label3:
  如n=label3，此处代码将执行；
  break;
default:
  如果n既不等于label1页不等于label2，此处代码将执行；
}

我们写一个程序，一个单选框。用switch语句半段。
程序如下：
