無法連接到MySQL服務器（2006錯誤）

Question

所以我最近使用MySQL，但一個非常奇怪的事情正在發生..

我希望我能在這裏找到一個解決方案！

<?php 
$servername = "theServername"; 
$username = "theUsername"; 
$password = "thePassword"; 
$dbname = "theDatabaseName"; 
$conn = new mysqli($servername,$username,$password,$dbname); 

if ($conn->connect_error) { 
    die("MySQL connection failed: " . $conn->connect_error); 
    echo "Couldn't connect."; 
} 
else { 
    echo "It connected."; 
} 
?> 

，並不斷出現我

警告：mysqli的:: mysqli的（）：MySQL服務器已消失在 C：\用戶\ STAR1 \ PhpstormProjects \上線的東西\ database.php中10

警告：mysqli :: mysqli（）：讀取問候數據包時出錯。 PID = 7520在C：\用戶\ STAR1 \ PhpstormProjects \上 線東西\ database.php中10

警告：mysqli的:: mysqli的（）（HY000/2006）：MySQL服務器已在 Ç消失：\用戶\ STAR1 \ PhpstormProjects \東西\ database.php中第10行 MySQL連接失敗：MySQL服務器已消失

和我10號線是$dbname這是new mysqli類的最後一個參數。

注：我把正確的信息放在字符串引號內，但這只是一個例子。

Answer 1

嘗試這個

$con = mysqli_connect($servername, $username, $password,$dbname);

Answer 2

$servername = "theServername"; 
$username = "theUsername"; 
$password = "thePassword"; 
$dbname = "theDatabaseName"; 
@$conn = new mysqli($servername, $username, $password, $dbname); 

if (mysqli_connect_errno()) { 
    die("MySQL connection failed: " . mysqli_connect_error()); 
    echo "Couldn't connect."; 
} else { 
    echo "It connected."; 
}
