Can't connect through PHP to an Access Database

问题

I have to establish a connection via PHP to a Access Database, but everytime I try I get this error:

Fatal error: Uncaught exception 'com_exception'

With message:

'Source: Microsoft OLE DB
Service Components
Description: Das Format der Initialisierungszeichenfolge entspricht nicht den OLE DB-Angaben.' in E:\path\to\phpfile.php:93
Stack trace: #0 E:\path\to\phpfile.php(93): com->Open('DRIVER={Microso...') #1 {main} thrown in

The German text means something like "the format of the initialization string is not common of the OLE DB statements.

My connection code looks like

$db = 'DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("\") & ("\\db\\db.mdb") & ";"';
$conn = new COM("ADODB.Connection"); 
$conn->Open($db);

I can't figure out what's wrong. In pure ASP it works fine, but not in PHP.

Thanks in advance

Instead of using the "ADODB.Connection" module use PDO since it's currently the best option out there and is a best practice, Here is the documentation: http://php.net/manual/en/book.pdo.php

But if PDO isn't for you then see ODBC (PDO RECOMMENDED) which is a native PHP module. Here is the documentation: http://php.net/manual/en/book.uodbc.php
To start a connection you would do this: $connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=$mdbFilename", $user, $password);

回答2:

Use PDO instead. It can connect via ODBC:

$pathToMDB = "path/to/db.mdb";
$db = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=$pathToMDB", 'admin');
