Opens a connection to a Microsoft SQL Server database. By default, the connection is attempted using Windows Authentication. To connect using SQL Server Authentication, include "UID" and "PWD" in the connection options array.

Parameters:

serverName

The name of the server to which a connection is established. To connect to a specific instance, follow the server name with a backward slash and the instance name (e.g. serverName\sqlexpress).

connectionInfo

An associative array that specifies options for connecting to the server. If values for the UID and PWD keys are not specified, the connection will be attempted using Windows Authentication. For a complete list of supported keys, see » SQLSRV Connection Options.

Returns:

A connection resource. If a connection cannot be successfully opened, FALSE is returned.

Examples:

Connect using Windows Authentication.

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

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

if( $conn ) {
     echo "Connection established.<br />";
