Question

我想使用核心 php 使用用户表中保存的凭据登录，我的密码以加密形式保存在数据库用户表中的 MD5 中，我想用电子邮件和密码登录，但是当我在登录密码时加密我的密码时与数据库表密码不匹配，请帮助我，我如何使用加密的 md5 密码登录。这是我的代码。

如何解散密码？

<块引用>

首先阅读我的评论。

散列

 password_hash ( string $password , mixed $algo , array $options = ? ) : string|false

用法：

<?php echo password_hash('Hello world', PASSWORD_BCRYPT ) ?>

值： $password = "密码";; $algo = "密码算法";

欲了解更多信息： https://www.php.net/manual/en/password.constants.php

将密码与散列版本进行比较##

  password_verify ( string $password , string $hash ) : bool

用法：

<?php $text = "I am a php master!"; $hashed = password_hash($text, PASSWORD_BYCRIPT); echo $text . "<br>". $hashed . "<br>";
   // password_verify returns a Boolean
   if(password_Verify($text, $hashed)) echo "Correct";   
  ?>

值：

密码

The user's password.

哈希

A hash created by password_hash().
