如何使用php連接MySQL數據庫（xampp）？

Question

我正試圖在phpstorm中連接到mysql數據庫，但我沒有成功。 我會感謝您的幫助。

<?php 
 
$servername = "http://localhost:8012"; 
 
$username = "root"; 
 
$password = ""; 
 

 
// Create connection 
 
$conn = new mysqli($servername, $username, $password); 
 

 
// Check connection 
 
if ($conn->connect_error) { 
 
    die("Connection failed: " . $conn->connect_error); 
 
}else{ 
 
die("Connected successfully"); 
 
}

的錯誤是：502錯誤的網關

Answer 1

您可以連接數據庫這樣的：

<?php 
$servername = "localhost"; 
$username = "root"; 
$password = ""; 
$database = ""; 
$port = "8012"; 

// Create connection 
$conn = new mysqli($servername, $username, $password, $database, $port); 

// Check connection 
if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error); 
}else{ 
die("Connected successfully"); 
} 

Answer 2

<?php 
 
$servername = "localhost:8012"; 
 
$username = "root"; 
 
$password = ""; 
 
$database = "dbname"; 
 

 
// Create connection 
 
$conn = mysqli_connect($servername, $username, $password,$database) or die(mysqli_error($conn); 
 

 
echo "Connection Successful";
