PHP文件實現接收用戶注冊／登陸數據功能
sign_up.php ?//接收用戶注冊數據
sign_in.php? //接收用戶登陸數據
MySQP存儲用戶登錄數據信息
使用PHP連接MySQP
PDO方式操作
登錄MySQL并創建數據庫
$servername = "localhost";
$DBName = "";
$DBUsername = "";
$DBPassword = "";
$conn = new PDO("mysql:host=$servername", ?$DBUsername, $DBPassword);
$sql = "create database $DBName";
conn->exec(sql);
echo "create db success" . "<br>";
鏈接數據庫并創建用戶表
$conn = new PDO( "mysql;host=$servername;dbname=$DBName", $DBUsername, $DBPassword);
$createtablesql = "";
$conn->exec($createtablesql);
echo "create table success" . "<br>"
