<?php $serverName = "127.0.0.1"; //serverName\instanceName $connectionInfo = array( "Database"=>"result2005", "UID"=>"user01", "PWD"=>"fire"); $conn = sqlsrv_connect( $serverName, $connectionInfo);

if( $conn ) {      echo "Connection established.<br />"; }else{      echo "Connection could not be established.<br />";      die( print_r( sqlsrv_errors(), true)); } ?>
