看看你就知道了
------解决方案--------------------
用SESSION保存验证码字符串,写个验证页面验证
------解决方案--------------------
是啊,前面这些都是好方法,楼主都可以借鉴一下!
------解决方案--------------------
图片php脚本生成图片后把验证码存在SESSION里,处理表单php就可以校验了。
------解决方案--------------------
if($ps&&($_POST["code"] == $_SESSION["code"])){
$_SESSION['name']=$row['name']; //获取name存入SESSION
$_SESSION['user_shell']=md5($row['email'].$row['password'].ALL_PS); //这里在对账号和密码进一层加密
$_SESSION['times']=mktime();
echo "您好:".$row['name']." 歡迎回來!"."退出";
}elseif(!$ps){
echo "用戶名或密碼錯誤!"."
";
}
elseif($_POST["code"] != $_SESSION["code"]){
echo "驗證碼有誤!";
}
session_destroy();
}

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
