[25-Feb-2017 09:45:09 UTC] PHP Warning: mysqli_connect(): (HY000/2003): Can't connect to MySQL server on 'mysql.hostinger.in' (4 "Interrupted system call") in /home/u191892126/public_html/API/connect.php on line 8

我的php文件：

<?php
$servername = "mysql.hostinger.in";//var deceleration I tried "localhost" too
$username = "u1918921**_root";
$password = "*********";
$dbname = "u191892126_acare";

}
?>
