Installing php_apc and php_curl on windows 64-bit systems

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. Now, 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.
