title: PHP startup mongo: Unable to initialize module
body: <p>I am currently Using <em>xampp</em> for <em>PHP</em>. I installed *mongo_db(1.8.5)* in my system and also installed <em>xampp-1.8.1-VC9</em> in my system. In order to configure PHP for <em>mongoDB</em>, I have downloaded *php_mongo.dll*(tried both <code>VC9 thread safe</code> and <code>non-thread safe</code>) and pasted the <em>.dll</em> file in the <em>'../php/ext'</em> directory and also added <code>extension=php_mongo.dll</code> in the <em>php.ini</em> file.</p>
  
  <p>Now when I try to start the <em>apache</em> in <em>xampp</em> it shows the following display eventhough <em>apache</em> is getting started.</p>
  
  <pre><code>PHP startup mongo: Unable to initialize module
  Module compiled with module API : 20090626
  PHP compiled with module API : 20100525
  These options need to match.
  </code></pre>
  
  <p>Also my <em>.php</em> code to connect <em>Mongo</em> is not working. This means there is something wrong somewhere.</p>
  
  <p>Where I am going wrong. Any help would be appreciated.</p>
