Cannot connect to SQL Server on local machine using PHP

[bigmac90]

I wonder if anyone can help me. I'm creating an application in PHP and am using a SQL server database on my local computer to develop the application. The only problem is I cannot connect to the database. My code looks like

<?php

$serverName = "LIAMJAY-PC\SQLEXPRESS"; //serverName\instanceName


$connectionInfo = array( "Database"=>"ONEDB");

$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));

}

?>

to connect to the database. However, everytime I run the code I keep getting a 18456 error code. Does anybody know what my problem is and if so, what is the solution???

$server = 'LIAMJAY-PC\SQLEXPRESS';
$link = mssql_connect($server, 'username', 'password');
if (!$link) {
    die(print_r( sqlsrv_errors(), true));
}

Try that, not tested.
