connect to mssql database via sqlsrv_connect() - PHP

问题

I'm attempting to connect to a 2005 Microsoft sql database using PHP by using the sqlsrv_connect() function. alas, the function returns false, and im not sure why.

<?php
$myServer = "MAZE.jpc.wa.edu.au.local";
$myUser = "myUsername";
$myPass = "myPassword";
$myDB = "John Paul College";
$connectionInfo = array("Database"=>$myDB, "UID" => $myUser, "PWD" => $myPass);

$conn = sqlsrv_connect($myServer, $connectionInfo); //returns false
if( $conn === false )
{
    echo "failed connection";
}

$sql = "SELECT name FROM users WHERE name= 'admin'";
$stmt = sqlsrv_query($conn,$sql);
if(sqlsrv_fetch($stmt) ===false)
{
    echo "couldn't fetch data"; 
}
$name = sqlsrv_get_field($stmt,0);
echo $name;
sqlsrv_close( $conn );
?>

Does anyone know why I can't connect? Thanks.

Edit.

Ok, well, i was able to bring up an error message thanks to the other guys answer, which states

I'm not entirely sure how to go about fixing this issue. I'm using XAMPP as my test webserver, php version 5.3 and the following .dlls php_sqlsrv_53_ts_vc6.dll and php_pdo_sqlsrv_53_ts_vc6.dll

回答1:

I would suggest that you display the connection error using sqlsrv_errors(). Please see the following implementation.

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

Download the SQL Native Client as the error message suggests. This is separate from SQL Server and a requirement for this driver to work correctly. Lesson learned from building an implementation of sqlsrv in an IIS environment
