本文實例講述了php+mysql實現用戶注冊登陸的方法。分享給大家供大家參考。具體分析如下：
這是一款利用php與mysql數據庫實現的用戶注冊與登錄代碼,功能也是比較簡單實用的用戶注冊程序,同時也加了用戶登錄時驗證碼程序,這樣做就安全了很多,代碼如下:
復制代碼 代碼如下:

<?php
require_once("config.php");
if(isset($_post["submit2"])){
mysql_select_db('a0807000225'); //這個是數據庫表
$author=$_session["user_name"];
define(all_ps,"jinquan");
echo $username=$_post["username"];
echo $password=md5($password=$_post["password"].all_ps);
echo "</br>";
if($username){
if($password){
$str = "insert into `dx_user_list` ( `uid` , `m_id` , `username` , `password` ) values (ascii( null ) , '1', '$username', '$password');";
$rs=mysql_query($str,$conn);
mysql_close($conn);
}
if($rs){
echo"<script>alert('新增成功');location.href='yonghuzc.php'</script>";
}else{
echo"<script>alert('新增失敗');location.href=''yonghuzc.php'</script>";
}
}
}
?>
