Question

我的代码有问题。我试图用pdo和php创建一个登录功能。当我尝试登录时，我发出消息：SQLSTATE [HY000] [2002]没有这样的文件或目录。

如果我没有创建一个函数（），只需将代码放在同一页面上即可。

我真的想了解这个问题，感谢所有帮助。

登录页面

<?php
include_once("../data/functions/index.php");


if(isset($_POST['login-btn'])) {

$email = strip_tags($_POST['email']);   
$password = strip_tags($_POST['password']);

DoLogin($email,$password);

}

功能文件

<?php

require_once("../data/connection/connect.php"); 

function DoLogin($email,$password) {

try
        {
          $conn = new PDO("mysql:host=$servername;dbname=$dbname", $uname, $pass);
          $stmt = $conn->prepare("SELECT * FROM users WHERE user_email = :email");
          $stmt->bindParam(':email', $email);
          $stmt->execute();
          $row = $stmt->fetch();

          $count = $stmt->rowCount();

          if($count > 0 && password_verify($password, $row['user_password'])) {             


            echo "YEEEEAAAAA BOOOOOIIII";

            }
            else {

                echo "fail :'(";
            }


        }



        catch(PDOException $e)
        {
            echo $e->getMessage();
        }

    }




?>

数据库连接文件

<?php
$servername = "x";
$uname = "x";
$pass = "x";
$dbname = "x";
try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $uname, $pass);
    // set the PDO error mode to exception   
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);


    }
catch(PDOException $e)
    {
    echo "Connection failed: " . $e->getMessage();
    }

    $conn == null;    

?>
