php - Warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: No such host is known -

i'm trying connect localhost database using php.

but it's shown

warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: no such host known. in c:\xampp2\htdocs\wikifiesto\wf-insertcase.php on line 7

warning: mysql_connect(): php_network_getaddresses: getaddrinfo failed: no such host known. in c:\xampp2\htdocs\wikifiesto\wf-insertcase.php on line 7 error connecting database

the structure of server, user, pass localhost, pma, ' '

here's code name 'wf-insertcase.php':

<?php define('dbuser', 'pma'); define('dbpass', ''); define('dbserver', 'localhost'); define('dbname', 'wikifiesto');  $conn = mysql_connect(dbuser, dbpass, dbserver, dbname);  if (!$conn) {     die('error connecting database'); }  echo 'you have created case'; ?> 

you have bad params order in function. db server has first param.

$conn = mysql_connect(dbserver, dbuser, dbpass); 

db name isn't allowed there, use mysql_select_db(dbname).

all mysql_* deprecated, see http://php.net/manual/en/function.mysql-connect.php , mysqli extension.

$conn = mysqli_connect(dbserver, dbuser, dbpass, dbname);              ^
