处理GET请求

实现的功能是输入姓名后页面显示“Hello XXX”

创建html文件hello.html：

<!DOCTYPE html>
<html>
<head lang="en">
  <meta charset="UTF-8">
  <title>欢迎</title>
</head>
<body>
<form action="hello.php" method="get">
  <input name="name" type="text"/>
  <input type="submit"/>
</form>
</body>
</html>

创建PHP文件hello.php：

<&#63;php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2015/6/30
 * Time: 15:03
 */
header("Content-type: text/html; charset=utf-8");
if(isset($_GET['name'])&&$_GET['name']){//如果有值且不为空
  echo 'Hello '.$_GET['name'];
}else{
  echo 'Please input name';
}

Get请求把表单的数据显式地放在URI中,并且对长度和数据值编码有所限制，如：http://127.0.0.1/hello.php?name=Vito

处理POST请求

实现一个简单的加法运算功能

创建html文件add.html:

<!DOCTYPE html>
<html>
<head lang="en">
  <meta charset="UTF-8">
  <title>相加</title>
</head>
<body>
<form action="add.php" method="post">
  <input name="num1" type="text"/>
  +
  <input name="num2" type="text"/>
  <input type="submit" value="相加"/>
</form>
</body>
</html>

创建PHP文件add.php：

<&#63;php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2015/6/30
 * Time: 18:02
 */


if($_POST['num1']&&$_POST['num2']){
  echo $_POST['num1']+$_POST['num2'];
}else{
  echo 'Please input num';
}

Post请求把表单数据放在http请求体中,并且没有长度限制

form action=""意思是：form是表单，action是转向地址，即form表单需要提交到哪里
