Fatal error: Call to undefined function mssql_connect() in C:\wamp\www\_inc\config.php on line 9

config:
<?php

$cfg['sql_host'] = "PC\SQLEXPRESS";
$cfg['sql_user'] = "silk";
$cfg['sql_pass'] = "password";
$cfg['sql_db'] = "SRO_VT_ACCOUNT";


$sqlLink = mssql_connect($cfg[sql_host],$cfg[sql_user],$cfg[sql_pass]);
if(!$sqlLink) die("MSSQL server is not accessable, why should we try to select database ?");
