How to enable PHP Locale class

I am using PHP 5.4.18 and am trying to use the Locale object. I have tried the following calls: ``` $locale = locale_accept_from_http($_SERVER['HTTP_ACCEPT_LANGUAGE']); $locale = Locale::acceptFromHttp($_SERVER['HTTP_ACCEPT_LANGUAGE']); ``` I get the errors 'Call to undefined function' and 'Class Locale not fund', respectively. I found a mention somewhere that the php_intl extension needs to be enabled. I did this. I've also looked at the Locale Manual(http://www.php.net/manual/en/class.locale.php), but there is not mention of needing to enable anything. What preparation do I need to undergo to enable the Locale class? Okie. I found that the php_intl file is not loading. However, it is present in the php/ext directory and the path it shows in the error log is correct. As a note: I am using WAMP.
