How do i connect to MSSQL database from php

Question

I have a Windows Azure Server and I want to connect to MSSQL server from a PHP application. But when i try to connect to the database it pops an error message saying...

Array ( [0] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Login failed for user 'NT AUTHORITY\IUSR'. [message] => [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Login failed for user 'NT AUTHORITY\IUSR'. ) [1] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Login failed for user 'NT AUTHORITY\IUSR'. [message] => [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Login failed for user 'NT AUTHORITY\IUSR'. ) ) 

I used this code to connect to the database..

<?php
    $serverName = "AZR-SRV-MAP01"; //serverName\instanceName

    // Since UID and PWD are not specified in the $connectionInfo array,
    // The connection will be attempted using Windows Authentication.
    $connectionInfo = array( "Database"=>"EmpSys");
    $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));
    }
?>

I'm accessing the database using Windows Authentication, therefore I'm not specifying the UID and PWD parameters.

Please assist me to connect to the SQL server.

Answer 2

The working code to connect to the MSSQL database from PHP (thanks to gofr1)..

<?php
    $serverName = "server_name"; //serverName\instanceName

    // Since UID and PWD are not specified in the $connectionInfo array,
    // The connection will be attempted using Windows Authentication.
    $connectionInfo = array( "Database"=>"db_name");
    $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));
    }
?>

EDIT

You need to turn Windows Authentication On, and set Anonymous Authentication Off in IIS settings. To authorize to SQL Server by your local/domain account.
