php接受透過HTML表單提交的資訊時,會將提交的資料保存在全域陣列中,我們可以呼叫系統特定的自動全域變數陣列來取得這些值。常用的自動全域變數如下所示:
$_GET
$_POST
實例程式碼
register.php:<html> <head> <meta http-equiv="Content-Type" content="text/html;charset=gb2312"> <title>注册页面</title> </head> <body> <form action="request.php" method="post" name="registForm"> <table width="330" border="0" align="center" cellpadding="5" bgcolor="#eeeeee"> <tr> <td width="40%">用户名:</td> <td><input name="username" type="text" id="username"/></td> </tr> <tr> <td>姓名:</td> <td><input name="name" type="text" id="name"/></td> </tr> <tr> <td>密码:</td> <td><input name="pwd" type="text" id="pwd"/></td> </tr> <tr> <td>邮箱:</td> <td><input name="email" type="text" id="email"/></td> </tr> <tr> <td colspan="2" align="center"> <input type="submit" value="提交" name="submit"/> <input type="reset" value="重置" name="button"/> </td> </tr> </table> </form> </body> </html>request.php
<?php $username = $_POST['username']; $name = $_POST['name']; $pwd = $_POST['pwd']; $email = $_POST['email']; //print_r($username); if(!empty($username)) { echo "您填写的信息为:<br>\n"; echo "用户名: $username <br>\n"; echo "姓名: $name <br>\n"; echo "密码: $pwd <br>\n"; echo "邮箱: $email <br>\n"; } print_r($_POST) //echo "aaaa"; ?>
