PHP Function HTTP Status Code Value as String

I’ve been working with the php CURL library and found that it would not return an error if the server returned a 500 error. After looking up 3 different status codes that I wasn’t very familiar with, I created the following function. It is very complete and includes additional WebDAV, Apache and Microsoft codes.

function http_status_code_string($code, $include_code=false)
{
	// Source: http://en.wikipedia.org/wiki/List_of_HTTP_status_codes

	switch( $code )
	{
		// 1xx Informational
		case 100: $string = 'Continue'; break;
		case 101: $string = 'Switching Protocols'; break;
		case 102: $string = 'Processing'; break; // WebDAV
