Setting up PHP extensions php_curl and php_apc on windows 7

• If you're using windows 64-bit OS, download the 64-bit TS VC9 compiled DLL files i.e. php_apc.dll
  and php_curl.dll, and store them in the PHP extensions directory.
• Enable these extensions in the PHP config file i.e. php.ini and you're good to go. 
• If you're using WAMP, the extension directory can be found in the C:\wamp\bin\php\php<version>\ext.
• If all went well, you can see the APC and CURL extensions in the phpinfo page. 
• To check PHP configuration settings on the server, create the following file, name it phpinfo.php and save it in c:\wamp\www folder.

  <?php
  echo phpinfo();
  ?>
  

• Now, browse to http://localhost/phpinfo.php and you'll see the PHP configuration and all the installed extensions.
