title: PHP can't connect to Mongodb
body: <p>I followed the windows installation instructions in mongodb's website but I still can't connect to MongoDB through PHP because of this error:</p>
  
  <p>Class 'Mongo' not found</p>
  
  <p>Why isn't the file containing the Mongo Class not being loaded?</p>
  
  <p>I've also found this error:</p>
  
  <p>PHP Warning:  PHP Startup: mongo: Unable to initialize module
  Module compiled with module API=20090626, debug=0, thread-safety=1
  PHP    compiled with module API=20060613, debug=0, thread-safety=1
  These options need to match
   in Unknown on line 0</p>
  
  <p>I'm using php 5.2.5 and the mongo-php-driver is Windows PHP 5.2 VC6 thread safe</p>
  
  <p>Thanks</p>
