Laba,

radau keistą situaciją HTTP2.php kode:

veikia:
  public function negotiateLanguage($supported, $default = 'en-US')
   ...
         if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
             $match = HTTP2::matchAccept(
                 $_SERVER['HTTP_ACCEPT_LANGUAGE'],
                 $supp
             );
   ...

bet neveikia originalas,
public function negotiateLanguage($supported, $default = 'en-US')
     {
....
         if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
             $match = $this->matchAccept(
                 $_SERVER['HTTP_ACCEPT_LANGUAGE'],
                 $supp
             );
....


'$this' kažkodėl būdu referr'ina į parent call'ą, t.y 
'MySite::sortAccept()', bet ne 'HTTP2::sortAccept()'

HTTP2 ką tik pastatytas iš pear'o.

'MySite' kodas
function MySite() {
....
  $this->lang = HTTP2::negotiateLanguage($langsAvailable);
....

Gal bus idėjų?
