无法使用php连接到服务器

Question

<?php
$host="localhost";
$user="user";
$password="debashree";
$connect=mysqli_connect($host,$user,$password);
if ($connect->connect_error) {
 die("connection_aborted".$connect->connect_error);
}
echo "connected succesfully";

这是mysql连接php脚本。一直显示错误

警告：mysqli_connect(): (HY000/1045): Access denied for user 'user'@'localhost' (using password: YES) in C:\xampp\htdocs\index.php on line 6

注意：试图在第 7 行的 C:\xampp\htdocs\index.php 中获取非对象的属性 连接成功

我看不懂请帮帮我？

您应该尝试进行以下更改：

<?php
try{
$host="localhost";
$user="user";
$password="debashree";
$databaseName = "myDB";
$connect=mysqli_connect($host,$user,$password, $databaseName);
if (**mysqli_connect_errno()**)
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
echo "connected succesfully";
}catch(Exception $e){
echo $e->getMessage();
}

另外，mysqli_connect 需要数据库作为第四个参数。

mysqli_connect("localhost","my_user","my_password","my_db");
