az önce php.nete girdiğimde 5.3.2 nin yayınlandığını okudum. 6.0 daki katılaştırılacak bazı kurallar şimdiden uygulanmaya başlanılmış 60 tan fazla bug’ın giderildiği bu sürümde deprecated fonksiyonlar arasına yeni fonksiyonlar eklemiş.
işleyişi değiştirecek en önemli değişiklik ise pointerlarda yapılmış bir artık new ike dönen bir obje referans alınamayacakmış nedenini çözemedim ama hayırlısı.. is_a fonksiyonunu da deprecatedlar arasından cıkarmışlar bu cok guzel olmuş (:
