PHP : Mongo class not found

Question

I am trying to run MongoDB with PHP. I have XAMPP 1.7.7 installed on my machine (Windows XP - 32 bit).

The PHP version is 5.3.8 and Apache version is 2.2.21. I installed the PHP MongoDB drivers as was given on their instructions page. I have the php_mongo.dll from this zip - mongo-1.1.4-php5.3vc9ts ( because i see that Thread Safety is enabled).

However, i always keep getting the message - 'Fatal error: Class 'Mongo' not found' for this code snippet-

$mongo = new Mongo();
$db = $mongo->database_name;

Does anyone know the solution to this ?

Thanks in advance.

Did you enable this module? Try `phpinfo();` to see is the module has been loaded — ajreal, Jun 04 '12 at 09:48
No. And yeah, i forgot to mention that too - the module is not being shown as loaded in phpinfo() (called from same script). I have added 'extension=php_mongo.dll' to the php.ini file too. Is there anything else to be done ? — Cygnus, Jun 04 '12 at 09:50
Have you restarted apache ? Did you put the dll into the path that can be read by apache? — ajreal, Jun 04 '12 at 09:54
Yeah, i did restart apache. Same error inspite of that. And i have put the dll into C:\xampp\php\ext\ . Is that fine ? — Cygnus, Jun 04 '12 at 09:56
Enable error logging in php (including start-up errors) and then restart apache and look in the error logs. That might tell you what's going on. — dakdad, Jun 04 '12 at 11:34
Error logging is on. The log contains the same record - 'Fatal error Class 'Mongo' not found' !! — Cygnus, Jun 04 '12 at 12:42

Please see this link - Error installing MongoDb PHP driver with XAMPP on Max OS Lion - I think it's possibly the same issue, though it was on Mac OS whereas you're on Windows.

I believe that you may need to install the xampp "Developer Package", required to build additional php extension.

The "Developer Package" can be found here : http://www.apachefriends.org/en/xampp-windows.html.

Thanks ! Although i didnt use it, the information here is quite useful and ill remember it for future reference. – Cygnus Jun 05 '12 at 10:58
No worries, good to know. A complete re-install sounds very extreme though! – Mark Hillick Jun 05 '12 at 11:10
Yeah, i know. But i needed it working fast and i was at my wit's end, so i thought of trying it !! – Cygnus Jun 06 '12 at 07:20

It's because you forgive something .. Mongo don't understand a class unknow so you have to do that :

$mongo = new MongoClient();
$db = $mongo->database_name;
