According to PHP documentation, HttpResponse is a static class to manipulate the Http response to the requester.
The code echo HttpResponse::getBufferSize();
throws the error in the Subject of this post.
Any ideas? Maybe it's some config, but I am a PHP newbie and I'm not sure where to look.
Thanks!
From the docs:
You need to install it via PECL http://pecl.php.net/package/pecl_http. To see how to install PECL, see (again) the docs.
If you haven't heard of PECL, read the Wikipedia page!
