我有2个项目1只是用来检查用户名和密码，如果它们存在于数据库中，它有password_verify（）函数的工作，另一个你可以注册然后登录，但是在这个1函数password_verify总是返回false，即使我已经在两个代码中写入了相同的代码，但是更改了表名，我将发布项目，所以如果有人可以帮助我。 我没有检查它是否正常连接到数据库并返回正确的电子邮件结果，但是当涉及到比较哈希传递和输入的邮件总是错误的。PHP password_verify返回false
的index.php是主要的页，并且只包含两个PHP行：
- 包括（ “signup.php”）;
- include（“login.php”）;
Connection.php
<?php
$server="localhost";
$db_username="myusername";
$db_password="mypassword";
$db="test_db";
$conn=mysqli_connect($server,$db_username,$db_password,$db);
if(!$conn)
die ("Connection Failed: ".mysqli_connect_error());
?>
signup.php
<?php
session_start();
if(isset($_POST['signup']))
{
function validateFormData($formData)
{
$formData=trim(stripcslashes(htmlspecialchars($formData)));
return $formData;
}
$email=validateFormData($_POST['email']);
$password=validateFormData($_POST['password']);
if(!$_POST['email'])
$error.="Please enter an email<br>";
else if(!filter_var($_POST['email'],FILTER_VALIDATE_EMAIL))
{
$error.="Please enter a valid email<br>";
}
if(!$_POST['password'])
$error.="Please enter a password<br>";
else
{
if(strlen($_POST['password'])<8)
$error.="Password must contain at least 8 characters<br>";
if(!preg_match('`[A-Z]`',$_POST['password']))
$error.="Password must contain at least one capital letter<br>";
}
if($error)
{
echo "<div class='alert alert-danger text-center lead'><a class='close red' data-dismiss='alert'>×</a>".$error."</div>";
}
else
{
include('connection.php');
$query="SELECT * FROM `diary` WHERE email='".mysqli_real_escape_string($conn,$email)."'";
$result=mysqli_query($conn,$query);
$results=mysqli_num_rows($result);
if($results)
echo "<div class='alert alert-danger text-center lead'>This email already exists, do you want to log in?<a class='close red' data-dismiss='alert'>×</a></div>";
else
{
$selectUser=mysqli_real_escape_string($conn,$email);
$hashedPass=password_hash($password,PASSWORD_DEFAULT);
$query="INSERT INTO `diary`(`email`, `password`) VALUES ('$selectUser','$hashedPass')";
mysqli_query($conn,$query);
echo "<div class='alert alert-success text-center lead'>You've been signed up!<a class='close green' data-dismiss='alert'>×</a></div>";
$_SESSION['id']=mysqli_insert_id($conn);
}
}
}
?>
的login.php
<?php
if(isset($_POST['login']))
{
function validateFormData($formData)
{
$formData=trim(stripcslashes(htmlspecialchars($formData)));
return $formData;
}
$formEmail=validateFormData($_POST['loginEmail']);
$formPass=validateFormData($_POST['loginPassword']);
$newPass=password_hash($formPass,PASSWORD_DEFAULT);
echo $newPass;
include("connection.php");
$query="Select * from diary where email='$formEmail' ";
$result=mysqli_query($conn,$query);
if(mysqli_num_rows($result)>0)
{
while($row=mysqli_fetch_assoc($result))
{
$LogEmail= $row['email'];
$LogPass= $row['password'];
echo "<br>".$LogPass;
}
if(password_verify($newPass,$LogPass))
{
echo "<br>Correct Password";
}
else
echo "<br>Not Correct";
}
}
?>
$ newPass的输出： “$ 2Y $ 10 $ dw0AtEExMc41p4nUB3W9kOOWTcNZmQev9jM4emNn7oQNODfu6Ld.q”
$ LogPass的输出是： “$ 2Y $ 10 $ biz6Z5nxsMZXNf7p3ebqw.pksPb1VhWEmoan776rMqOC7VcFRQbrK”

我试了一下没有这个功能，但还是一样 –
我可以发送你这个项目，它只有注册和登录，也许你可以得到更好的知识，什么问题可能 –
哈希是密码，我没有检查 –
