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:
1
2
3
4
5
6
7
8
9
10
11
12

<!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:
1
2
3
4
5
6
7
8
9
10
11

<?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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14

<!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:
1
2
3
4
5
6
7
8
9

<?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
