Question

我目前拥有Google的Cloud SQL数据库和Namecheap的Web / PHP服务器。我正在尝试使用我的Namecheap服务器中的PHP脚本来连接数据并将数据插入到我的Cloud SQL DB中的表中。我的PHP脚本适用于我的Namecheap帐户提供的数据库，但不适用于我为新的Cloud SQL连接创建凭据和主机更改。我知道我可以通过我的IP建立连接并且它们是正确的，因为我可以从MySQL Workbench连接到Cloud SQL DB。

错误：

[11-Oct-2017 19:28:12 America/New_York] PHP Warning:  mysqli_connect(): 
(HY000/2003): Can't connect to MySQL server on '35.199.10.53' (111

欢迎任何建议，以下是我的代码。

googlemule.php

<?php
    function db_connect() {

        // Define connection as a static variable, to avoid connecting more than once 
    static $muleconnection;

        // Try and connect to the database, if a connection has not been established yet
    if(!isset($muleconnection)) {
             // Load configuration as an array. Use the actual location of your configuration file
        $config = parse_ini_file('/home/dumamwny/private/googlemule.ini'); 
        $muleconnection = mysqli_connect($config['servername'],$config['username'],$config['password'],$config['dbname']);
    }

        // If connection was not successful, handle the error
    if($muleconnection === false) {
            // Handle error - notify administrator, log to a file, show an error screen, etc.
        return mysqli_connect_error(); 
    }
    return $muleconnection;
    }

    // Connect to the database
    $muleconnection = db_connect();

    // Check connection
    if ($muleconnection->connect_error) {
    die("Connection failed: " . $muleconnection->connect_error);
    }
    ?>

php2.php

<?php
require_once('googlemule.php');

$charName = $_POST['charName'];
$logType = $_POST['logType'];
$magicPrice = $_POST['magicPrice'];
$magicAmount = $_POST['magicAmount'];
$yewPrice = $_POST['yewPrice'];
$yewAmount = $_POST['yewAmount'];
$totalWealth = $_POST['totalWealth'];

$sql = "INSERT INTO dumaismule (char_name, log_type, magic_log_price, 
magic_log_amount, yew_log_price, yew_log_amount, total_wealth)
VALUES ($charName, $logType, $magicPrice, $magicAmount, $yewPrice, 
$yewAmount, $totalWealth)";


$query = $muleconnection->query($sql);
echo 'OK..';

?>

无法使用php
