//本地连接 
$servername = "cx95dlisvw4c6tk\aaa";//计算机名\实例名 
$connectioninfo = array("database"=>"fff","connectionpooling"=>'','uid'=>'sa','pwd'=>'123'); 
$conn = sqlsrv_connect( $servername, $connectioninfo); 
if( $conn == false) 
{ 
    echo "连接失败！"; 
    die( print_r( sqlsrv_errors(), true)); 
}else{ 
echo "dfdf"; 
$query=sqlsrv_query($conn,"select * from dbo.fdsf"); 
while($row = sqlsrv_fetch_array($query)){ 
print_r($row); 
     } 
//print_r($query); 
} 

//远程连接 
$servername = "192.168.1.5"; 
$connectioninfo = array("database"=>"cia","connectionpooling"=>'','uid'=>'sa','pwd'=>'360kad.com'); 
$conn = sqlsrv_connect( $servername, $connectioninfo); 
if( $conn == false) 
{ 
    echo "连接失败！"; 
    die( print_r( sqlsrv_errors(), true));
