Question

我写了这段代码，执行时我得到的只是白屏

我检查了旧问题，并尝试了

之类的许多解决方案

ini_set（'display_startup_errors'，true）;

error_reporting（E_ALL）;

ini_set（'display_errors'，true）;

<?php

$host = "localhost";
$username = "root";
$password = "";
$dbname = "users";
try {
$connexion = new PDO("mysql:host=$host;dbname=$dbname",$username, $password);
$connexion -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch(PDOException $e) {
    echo $e->getMessage();
}


ini_set('display_startup_errors', true);
error_reporting(E_ALL);
ini_set('display_errors', true);




    if (isset($_POST['Connexion'])){
$errMsg = '' ;
$email = $_POST['mail'];
$pass = $_POST['pass'];
if($email == ''){
    $errMsg = 'Enter username';
}
if($pass == ''){
    $errMsg = 'Enter password';
}

if( $errMsg == '') {
    try {
        $stmt = $connexion->prepare('SELECT * FROM users WHERE mail = :mail ');
        $stmt->execute(array(':mail' => $email ));  
        $data = $stmt->fetch(PDO::FETCH_ASSOC);
        if($data == false ){
            $errMsg = "User  not found.";
        }
        else {
                if($password == $data['password']) {
                    $_SESSION['first_name'] = $data['first_name'];
                    $_SESSION['last_name'] = $data['last_name'];
                    $_SESSION['password'] = $data['password'];
                    header('Location: ../profil/profil.php');               
                    exit;
                }
                else{
                    $errMsg = 'Password not match.';
                }
        }
    }
    catch(PDOException $e) {
        $errMsg = $e->getMessage();
    }
}
}   


?>

这是html页面

<!DOCTYPE html>
<html>
<head>
    <title>login page</title>
    <meta charset='utf-8'>
    <link rel="stylesheet" href="login-html-css-php (2).css">

</head>
<body>
<form method="POST" action="sign-in.php" >
    <div class= login>

        <div class = log>
            <h1 id="sign-in"> Login </h1>

            <div class= A>
            <i class="fas fa-envelope"></i>
            <input  class= type= "email"  id = "email" name= "mail" placeholder="mail" >
            </div>

            <div class= A>
            <i class="fas fa-lock"></i>
            <input type= "password" id = "pass" name= "pass"  placeholder="password">
            </div>

            <div class= C>
            <input type="submit" value= "Connexion" id="disp_button" name="Connexion">
            </div>

        </div> 
    </div>                  
</form>

但浏览器仍显示白页

请提出任何建议，我认为错误来自我的代码

谢谢
