本文实例为大家分享了PHP实现简单注册登录系统的具体代码,供大家参考,具体内容如下
目录结构如下,其中function文件夹下包含两个函数文件,uploads文件夹用于存放上传的文件。
注:博主使用的是php5,使用php7的小伙伴运行报错的话有一部分原因是新的语法造成的,修改成新语法就可以了
html页面
登录页面
index.html
注册页面
register.html
用户注册登录系统
功能实现文件
实现登录功能
login_process.php
<?php include_once("function/database.php"); // $userName = $_POST["userName"]; // $password = $_POST["password"]; $userName = addslashes($_POST["userName"]); $password = addslashes($_POST["password"]); getConnect(); $loginSQL = "select * from users where userName="$userName" and password="$password""; echo $loginSQL; $resultLogin = mysql_query($loginSQL); if (mysql_num_rows($resultLogin) > 0) { echo "登录成功"; } else { echo "登录失败"; } closeConnect(); ?>
实现注册功能
register.php
<?php include_once("function/fileSystem.php"); include_once("function/database.php"); if (empty($_POST)) { exit("您提交的表单数据超过post_max_size!
"); } // 判断输入密码与确认密码是否相同 $password = $_POST["password"]; $confirmPassword = $_POST["confirmPassword"]; if ($password != $confirmPassword) { exit("输入的密码与确认密码不相等!"); } $userName = $_POST["userName"]; $domain = $_POST["domain"]; $userName = $userName . $domain; // 判断用户名是否重复 $userNameSQL = "select * from users where userName = "$userName""; getConnect(); $resultSet = mysql_query($userNameSQL); if (mysql_num_rows($resultSet) > 0) { exit("用户名已被占用,请更换其他用户名"); } $sex = $_POST["sex"]; if (empty($_POST["interests"])) { $interests = ""; } else { $interests = implode(";", $_POST["interests"]); } $remark = $_POST["remark"]; $myPictureName = $_FILES["myPicture"]["name"]; $registerSQL = "insert into users values(null, "$userName", "$password", "$sex", "$interests", "$myPictureName", "$remark")"; $message = upload($_FILES["myPicture"], "uploads"); if ($message == "上传成功" || $message == "没有上传") { mysql_query($registerSQL); $userID = mysql_insert_id(); echo "注册成功
"; } else { exit($message); } $userSQL = "select * from users where user_id = "$userID""; $userResult = mysql_query($userSQL); if ($user = mysql_fetch_array($userResult)) { echo "您的注册用户名为:" . $user["userName"]; } else { exit("用户注册失败!"); } closeConnect();
函数文件(function文件夹)
实现数据库连接与关闭的函数
database.php
<?php $databaseConnection = null; function getConnect() { $hosthome = "localhost"; $database = "register"; $userName = "root"; $password = "123456"; global $databaseConnection; $databaseConnection = @mysql_connect($hosthome, $userName, $password) or die (mysql_error()); mysql_query("set names gbk"); @mysql_select_db($database, $databaseConnection) or die (mysql_error()); } function closeConnect() { global $databaseConnection; if ($databaseConnection) { @mysql_close($databaseConnection) or die (mysql_error()); } } ?>
实现文件上传的函数
fileSystem.php
<?php function upload($file, $filePath) { $error = $file["error"]; switch ($error) { case 0: $fileName = $file["name"]; $fileTemp = $file["tmp_name"]; $destination = $filePath . "/" . $fileName; move_uploaded_file($fileTemp, $destination); return "上传成功"; case 1: return "上传超过upload_max_filesize"; case 2: return "上传文件超过form的MAX_FILE_SIZE"; case 3: return "附件部分上传"; case 4: return "没有上传"; } } ?>
