Re: Fatal error: Call to a member function on a non-object

Did you upgrade Zend Optimizer when you upgraded to 4.3.10 ? People are seeing quite a few problems when they dont, and this could be releated to that. Chris Tim Burgan wrote:

Hello, I have a database driven (MS Access 2000) PHP website that runs fine on my localhost (Apache, WinXP, PHP 4.3.9), but when I upload it to the web host (IIS, PHP 4.3.10) and try to access a page I receive the following error: Fatal error: Call to a member function on a non-object in c:\XXX\inc\dbConnOpen.php on line 17 The file in question contains code that forms a connection to the database. I've used this EXACT same code on this same website for the last 8 months (both on localhost and web host) with no problem.. then when I upload the WHOLE site again.. it doesn't work. Here's the contents of the above file: /* Open database connection */ $db_connection = new COM("ADODB.Connection") or die("Cannot start ADO");

  $db_connstr    = "DRIVER={Microsoft Access Driver (*.mdb)};DBQ=" .
                    realpath("directory/database.mdb") . ";DefaultDir=" .
                    realpath("directory");
  $db_connection->open($db_connstr);      // THIS IS LINE 17

Can anyone shed some light onto what this error means in plain english, and possible what I can do. Thanks for your time.. I'm in a bit of a pickle. Cheers Tim
