Problems on PHP5 object instantiation

Hi, I'm now trying OOP in PHP5, and enjoy it very much. However, as we know PHP5 does not allow compile-time instantiation, so when I try this script: <?php class C { static private $o = new stdClass(); } ?> it ends up with a parse error, while in Java it works naturally. I wonder whether there are some difficulties on implementing this feature, or, is it just not the natural way? Thanks :) -- Best regards, Jingcheng Zhang Room 304, Dormitory 26 of Yuquan Campus, Zhejiang University P.R.China
