title: 32bit and 64bit ODBC Drivers playing nice with PHP
body: <p>I am running PHP on a 64bit windows 2008 server. I have both ODBC 32bit and 64bit installed and I attempt to do this:</p>
  
  <pre><code>$dbh = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=$mdbFilename", $username, $password);
  </code></pre>
  
  <p>The 32bit ODBC install has the driver <code>Microsoft Access Driver (*.mdb)</code> and the 64bit version has the <code>Microsoft Access Driver (*.mdb, *.accdb)</code> which is what I need but PHP says it cant find it and I am assuming PHP is only referencing the 32bit ODBC driver.</p>
  
  <p>Why is this the case? Is it as simple as PHP/Apache being a 32 bit install?</p>
  
  <p>Thanks all for any help</p>
