在本地主机 XAMPP 上连接的这个 PHP 代码有什么问题

Question

The error is: Connection failed: SQLSTATE[HY000] [1045] Access denied for user 'moomen'@'localhost' (using password: YES)

Code is:

<?php
$servername = "localhost";
$username = "moomen";
$password = "9124279123";
$dbname = "ecocaa";
try {
$conn = new PDO("mysql:host=$servername;dbname=$servername", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully";

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