无法将PHP与MSMSQL连接

Question

我已经编写了以下PHP代码，但无法连接到ms sql服务器

<?php   

echo "Create the Connection...<br  />";
$connection = odbc_connect('SQLServer', '', '');

echo "Test Connection...<br />";
if($connection){
  echo "Yep , we are live !";
 }

$query =<<<E0F
Select * from [Addy].[dbo].[Adnan]
 E0F;

 $rs= odbc_exec($connection,$query);

  odbc_result_all($rs,"cellpadding='3'
  background-color='d3d3d3'");
