I am using this code to log in to sql server express 2012
<?php
$serverName = "SD-20120627VVKE\SQLEXPRESS";
$connectionOptions = array("Database"=>"android_api");
$conn = sqlsrv_connect( $serverName, $connectionOptions);
if( $conn === false )
{ die( FormatErrors( sqlsrv_errors() ) ); }
?>
but I get this screen

How should I solve it?
Try this:
