php中$_POST变量是一个数组，用于收集来自method="post"的值，内容是有HTTP POST方法发送的变量名称和值。
从带有POST方法的表单发送的信息，对任何人都是不可见的，并且发送的信息也没有限制。
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>feiruo</title> </head> <body> <form action="welcome.php" method="post"> name: <input type="text" name="name" /> age: <input type="text" name="age" /> <input type="submit" /> </form> </body> </html>
<?php
echo "Your name is '$_POST['name']', you are '$_POST['age']'.";
?>
$_REQUEST变量包含了$_GET，$_POST方法以及$_COOKIE内容，因此可以使用$_REQUEST变量来获取通过$_GET和$_POST方法发送的数据结果。
其实学PHP有好些时间了，但是还没有好好练习过，今天使用AS3.0调用PHP文件将数据写入到mySQL数据库。
下面是PHP文件register.php:
<?php header("Content-Type:text/html;charset=utf-8"); define('DB_USER', 'localhost'); define('DB_ROOT', 'root'); define('DB_PWD', 'eXdA8hP954ABzVD8'); define('DB_NAME', 'feiruodata'); $getName=$_POST['_name']; $getPswd=$_POST['_pswd']; //连接mySQL $con=@mysql_connect(DB_USER,DB_ROOT,DB_PWD)or die('连接错误'); //选择数据库 mysql_select_db(DB_NAME,$con)or die('Occured error'); mysql_query('SET NAMES UTF8') or die('显示错误'); $query="INSERT INTO excise01 (user_name,user_pswd) VALUES ('$getName','$getPswd')"; $row=@mysql_query($query) or die('cuowu'); //关闭数据库 mysql_close(); ?>
