php的属性默认就是public,  这关键字简直可以删掉，可以提高可读性.
没听说过删除这个还可以提高可读性强烈建议加上public，包括function，这样可读性更高，对于以后的PHP版本也会更兼容

另外发现了一些问题，比如函数的参数的问题，，post($path,$referer="",$cookie="",$jump=1,$returnCode="",$data="")这样的不合理，有默认值的参数应该放在最后，代码中多次出现。基础知识有所欠缺
呵，我没看具体的代码，只看到public $toolType = 1;     //1:curl,2:socket,3:Stream这一句的时候，就知道，LZ应该是有优化的余地，至于怎么优化，就不讲了，还有就是觉得如果硬是要写成CLASS，那还是利于写成CLASS的样子，结构性上可以好好重新考虑一下，你的功能也许是很有用，但结构上我想不好好考虑，实用性上也是值得商榷的。
