无法连接到MSSQL Server

Question

当我尝试使用以下代码建立与MSSQL Server的连接时：

try {
$c_info = array("Database" => "ddb", "UID" => "sa", "PWD" => "admin123");
echo var_dump(sqlsrv_errors(SQLSRV_ERR_ALL));

$db = sqlsrv_connect('LENOVOWIH\SQLEXPRESS', $c_info); // Make a connection to MSSQL
if($db) echo '\ntrue';
else echo "\nfalse : " . var_dump(sqlsrv_errors());
}  catch(Exception $e) {
      echo $e . " " . sqlsrv_errors();
   }

var_dump(sqlsrv_errors())发出：

    array (size=2)
  0 => 
    array (size=6)
      0 => string 'IMSSP' (length=5)
      'SQLSTATE' => string 'IMSSP' (length=5)
      1 => int -49
      'code' => int -49
      2 => string 'This extension requires the ODBC Driver 11 for SQL Server. Access the following URL to download the ODBC Driver 11 for SQL Server for x86: http://go.microsoft.com/fwlink/?LinkId=163712' (length=184)
      'message' => string 'This extension requires the ODBC Driver 11 for SQL Server. Access the following URL to download the ODBC Driver 11 for SQL Server for x86: http://go.microsoft.com/fwlink/?LinkId=163712' (length=184)
  1 => 
    array (size=6)
      0 => string 'IM002' (length=5)
      'SQLSTATE' => string 'IM002' (length=5)
      1 => int 0
      'code' => int 0
      2 => string '[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified' (length=91)
      'message' => string '[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified' (length=91)

我已将extension=php_sqlsrv_55_ts.dll放入php.ini （\ wamp \ bin \ apache \ apache2.4.9 \ bin \ php.ini）文件中dll在ext目录中。我正在使用php版本5.5.12

的wampp

这可能是什么原因？

Answer 1

安装ODBC driver。 sqlsrv驱动程序基于ODBC构建，由Microsoft主动维护，并提供对SQL Server最新版本中的功能的访问。
