在项目开发中经常见到不同页面之间传值在web工作中，本篇文章给大家列出了三种常见的方式。

接触PHP也有几个月了，本文总结一下这段日子中，在编程过程里常用的3种不同页面传值方法，希望可以给大家参考。有什么意见也希望大家一起讨论。

一. POST传值

post传值是用于html的

表单跳转的方法，很方便使用。例如：

 <html>
 <form action='' method=''>
 <input type='text' name='name1'>
 <input type='hidden' name='name2' value='value'>
 <input type='submit' value='提交'>
 </form>
 </html>

form中的action填入的是跳转页面的url路径,method填入post方法。form表单中的提交按钮按下后，就会把form中有name的内容都传到填入的url中，可以通过$_POST['name']获取，例如:

<&#63;php
$a=$_POST['name1'];
$b=$_POST['name2'];
&#63;>

这里有个很方便的小技巧，在input标签中把type选为'hidden'时，这个input标签会隐藏起来，不在页面显示，但这input标签在form中，并且有name值和value值，同样会跟随提交按钮传递过去，这种隐藏标签可以传递一些不想显示出来的内容。

二.GET传值

GET传值是通过跟随url传递的，在页面跳转时，跟着url跳转。常用于标签的使用。例如：

<a href='delete.php&#63;id=value'>点我跳转</a>

跳转进入xxx.php后，就能通过$_GET['id']获取传递的值。GET方法常用于URL的目的是删除或读取某个id的php文件。

三.SESSION传值

SESSION是全局变量的一种，经常用于用户登陆后保存用户id之类的常用数据。一旦保存到SESSION中，其他页面都可以通过SESSION获取,SESSION的使用要开启session：

<&#63;php
//session赋值
  session_start();
  $_SESSION['one']=value1;
  $_SESSION['two']=value2;
//session值的读取:
  $one = $_SESSION['one'];
  //session值的销毁
  unset($_SESSION['one']);
&#63;>

以上是小编给大家列出的三种方式，供大家参考，同时希望大家喜欢。

php和html之间的传值问题

这样的表单我用form怎么向php传值，重点是php怎么接收这样的数据

------解决思路----------------------

form表单里两个参数，一个action，表明了往哪个文件传，不写默认传自己；一个method，表明用什么方式传，有get和post两种

input框加name

接受的文件里用$_POST（post方式）或者$_GET（get方式）接收。最简单的是直接var_dump($_POST)或者var_dump($_GET)然后你就知道怎么调用了
