cpanel登录网站文件夹时的php警告

Question

I am writing some php script in the cpanel. When I access the website folder (e.g. www.bbbbbb.com/folder/) It give the warning like that.

Warning: mysqli::mysqli() [mysqli.mysqli]: (HY000/2005): Unknown MySQL server host    'host07.portalwebhosting' (1) in /home/restaur/public_html/restaurant/variables/variables.php on line 7

Warning: mysqli::set_charset() [mysqli.set-charset]: Couldn't fetch mysqli in /home/restaur/public_html/restaurant/includes/connect_database.php on line 3

Warning: mysqli::stmt_init() [mysqli.stmt-init]: Couldn't fetch mysqli in /home/restaur/public_html/restaurant/includes/login_form.php on line 45

Fatal error: Call to a member function prepare() on a non-object in /home/restaur/public_html/restaurant/includes/login_form.php on line 46

And I use the default account admin to access, it gives me the same result.

And here is my php coding

<?php
// database configuration
$host ="host07.portalwebhosting.com";
$user ="user";
$pass ="password";
$database = "monkey";
$connect = new mysqli($host, $user, $pass,$database) or die("Error :    ".mysql_error());

// access key to access API
$access_key = "12345";?>

Answer 1

check your connection string or may be you need to try with port

$connection = new mysqli("host", "user", "pwd", "db", "3306");

no need to change port 3306 is default why you use die("Error : ".mysql_error()); use mysqli
