PHP连接access数据库，一直不成功，大家帮忙分析一下

[dangsz]

$db1="D:\phpstudy_pro\WWW\Data.mdb";
$db2=realpath("Data.mdb");
$db3=$_SERVER['DOCUMENT_ROOT'] . "/Data.mdb";


//第一种方式正常
$conn = new com("ADODB.Connection");
$connstr = "DRIVER={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=" . $db2;
$connid=odbc_connect($connstr,"","",SQL_CUR_USE_ODBC );
$sql="select * From Users";
$rs=odbc_exec($connid,$sql);
echo odbc_result($rs,"LoadPass");
odbc_close($connid);
//这种方式可以正常查询记录

//地二种方式错误
$conn = @new com("ADODB.Connection") or die ("ADO连接失败!");
//$connstr = "DRIVER={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=" . $db2;
$connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . $db2;
$conn->Open($connstr); //这行提示：Fatal error: in

为什么第二种方式不行呢？折磨我两天了

    $db1="F:\WWW\Data.mdb";
    $conn = new com("ADODB.Connection");
    $connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . $db1;
    $connstr = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" . $db1;
    $connstr = "DRIVER={Microsoft Access Driver (*.mdb, *.accdb)}; DBQ=" . $db1;
    echo $connstr . "<br>";
    $conn->Open($connstr);

三种方法都出错：错误一样
Fatal error: in F:\WWW\Index.php on line 57

    $db1="F:\WWW\Data.mdb";
    $conn = new com("ADODB.Connection");
    $connstr = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" . $db1;              //尝试这个Open处 Fatal error 错误
    $connstr = "Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=" . $db1;   //尝试这个Open处 Fatal error 错误
    $connstr = "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" . $db1;            //尝试这个Open处 Fatal error 错误
    $connstr = "PROVIDER=Microsoft.ACE.OLEDB.12.0; Data Source=" . $db1;   //尝试这个Open处 Fatal error 错误
    $connstr = "PROVIDER=Microsoft.ACE.OLEDB.16.0; Data Source=" . $db1;   //成功
    echo $connstr . "<br>";
    $conn->Open($connstr);

    echo "<br><font style='color:green;font-weight:bold;'>连接数据库成功</font><br>";

    $conn->Execute("Insert into T (A) values ('zhongguo')");          //成功

    $conn->Execute("UpDate T Set A='dfagtaeyrg' Where ID=1"); //成功

    $conn->Execute("Delete From T Where ID=2");                       //成功

    $conn->Execute("Select A From T Where ID=3");                 //尝试这个Open处 Fatal error 错误

    $result=$conn->Execute("Select * From T Where ID=3");     //尝试这个Open处 Fatal error 错误

    $rs = new COM("ADODB.RecordSet");
    $rs->Open("Select * From T Where ID=3",$conn,1,1);          //尝试这个Open处 Fatal error 错误
    echo $rs->Field['A'].value;

现在是可以添加 ，修改，删除 ，就是不可以查询记录？
快疯了
