PDO:php

<?php
/*$conn = mysql_connect('localhost','root','root');
mysql_select_db('db_shcool');
$result = mysql_query ('select*from stu2');*/
//print_r(mysql_fetch_array($result));
//print_r(mysql_fetch_array($result));

數據庫連接註冊登陸mysql

註冊登陸總頁面：sql

<!DOCTYPE html>
<html>
   <head>
       <meta charset="utf-8" />
       <title></title>
   </head>
   <body>
       <a href="html/reg.html">註冊</a>
       <a href="html/login.html">登陸</a>

   </body>
</html>
連接註冊頁面註冊頁面內要有數據庫超連接註冊頁面內填寫信息：數據庫

<!DOCTYPE html>
<html>post

   <head>
       <meta charset="UTF-8">
       <title>註冊</title>
   </head>fetch

   <body>
       <form action="../action/reg.php" method="post">
       用戶名：<input type="text" name="name" /><br> 密碼： <input type="password" name="pwd" /><br> 確認密碼：
       <input type="password" name="rpwd" /><br> 聯繫電話： <input type="text" name="tel" /><br>
       <input type="submit" value="註冊" />
       </form>
   </body>url

</html>orm

數據庫鏈接：htm

<?php
include_once '../libs/fn_comm.php';

$name = $_POST['name'];
$pwd = $_POST['pwd'];
$rpwd = $_POST['rpwd'];
$tel = $_POST['tel'];
refresh();
if($pwd == $rpwd){
   $dsn = 'mysql:host=localhost;dbname=z_lign';
$opt = array(PDO::MYSQL_ATTR_INIT_COMMAND => 'set names utf8');
$pdo = new pdo ($dsn, "root","root",$opt);
$pwd = md5($pwd);
$sql = "INSERT INTO account(`name`,`pwd`,`tel`) VALUES('".$name."','".$pwd."','".$tel."')";
$rs = $pdo -> exec ($sql);
if($rs == 1){
   echo '<h1>註冊成功</h1>';
}
} else {
   echo '<h1>密碼不一致</h1>';
}

數據庫鏈接內有自動跳轉頁面：

<?php
function refresh ($sec = 2, $url = 'http://localhost/test'){
header ('content-type: text/html;charset=utf8');
header('refresh:' . $sec . ';' . $url);

}

?>

登陸頁面頁面內有數據庫連接：

<!DOCTYPE html>
<html>

</html>
數據庫鏈接：

<?php
include_once '../libs/fn_comm.php';

$name = $_POST['name'];
$pwd = $_POST['pwd'];
$dsn = 'mysql:host=localhost;dbname=z_lign';
$opt = array(PDO::MYSQL_ATTR_INIT_COMMAND => 'set names utf8');
$pdo = new pdo ($dsn, "root","root",$opt);
$pwd = md5($pwd);
$sql = "select * from account where `name`='".$name."'and `pwd` ='".$pwd."'";
$rs = $pdo -> query ($sql);
if($rs-> fetch()){
echo '<h1> 登陸成功！</h1>';

} else {
echo '<h1> 登陸失敗！</h1>';
}

註冊登陸表完成！
