获取连接超时与DB连接

Question

我试图连接到远程Rackspace公司DB PHP：

<?php 
    $servername = "XX.XX.XX.XX"; 
    $username = "username"; 
    $password = "password"; 
    $dbname = "table"; 
    // Create connection 
     $conn = new mysqli($servername, $username, $password, $dbname); 
    // Check connection 
     if ($conn->connect_error) { 
     die("Connection failed: " . $conn->connect_error); 
    } 
?> 

我也得到警告：mysqli的:: mysqli的（）（HY000/2002）：连接超时出 任何建议

Answer 1

试试这个

<?php 
     $servername = "XX.XX.XX.XX"; 
     $username = "username"; 
     $password = "password"; 
     $dbname = "table"; 
     // Create connection 
      $conn = mysqli_connect($servername, $username, $password, $dbname); 
     // Check connection 
      if (mysqli_connect_errno()) { 
     echo "Failed to connect to MySQL: " . mysqli_connect_error();die(); 

     } 
    ?>
