php - Can't connect on database on my localhost -


i have php script:

 <?php  $host     = $_get['host']; $username = $_get['username']; $pass     = $_get['pass'];  $con = mysql_connect($host, $username, $pass); if (!$con) {     echo 'connection failed!'; } else {     echo 'connected successfully!'; } mysql_close($con);  ?>

running on remote server , when execute , try connect database located on pc error:

warning: mysql_connect() [function.mysql-connect]: can't connect mysql server on '109.60.110.255' (4) in /home/a6859995/public_html/zavrsni/connect.php on line 12

how can fix that?

i recommend use pdo this:

class_config.php:

class class_config {      public static $db_host = 'localhost';     public static $db_name = 'yourdbname';     public static $db_user = 'youruser';     public static $db_pass = 'yourpass';  }

class_pdo.php:

require_once "class_config.php"; class class_pdo {      public static function dbfactory() {         $host = class_config::$db_host;         if(strpos($host,":") !==false) {             $parts = explode(":",$host);             $hostname = "unix_socket=".$parts[1];         } else {             $hostname = "host=$host";         }         $user = class_config::$db_user;         $pass = class_config::$db_pass;         $dbase = class_config::$db_name;                 $pdo = new pdo("mysql:$hostname;dbname=$dbase", $user, $pass);         $pdo->setattribute(pdo::attr_errmode, pdo::errmode_exception);         $pdo->setattribute(pdo::attr_emulate_prepares, false);                 return $pdo;     } }

use in script this:

require_once("class_pdo.php");  $pdo = class_pdo::dbfactory();  $stmt = $pdo->prepare("select * `tablename` id = :id "); $stmt->bindvalue(":id", $id, pdo::param_int); $stmt->execute();  [...]
