title: Installing Apache Solr on Windows WAMP Server
body: <p>I tried to install Apache Solr on WAMP server (in Windows) and I succeeded but the problem was that I couldn't use the PHP Solr library on this environment. The error I keep getting is:</p>
  
  <pre><code>PHP Warning:  PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.4.12/ext/php_solr.dll' - %1 is not a valid Win32 application.\r\n in Unknown on line 0.
  </code></pre>
  
  <p>I've downloaded, included and activated the dll file containing the PHP Solr library but this error keeps comming.</p>
  
  <p>PHP version: 5.4.12<br />
  Wampserver version: 2.4</p>
