在学习PHP这六个月里,每看到一个优秀的php脚本,就会兴奋的手舞足蹈,嘴里还不停的说:太酷了,太酷了。呵呵,很幼稚吧,但这可能就是兴趣。谷歌 比来对谷歌的PageRank对照感乐趣,一向想晓得若何不必谷歌 toolbar来获得pr值。用嗅探东西取得谷歌 toolbar收回恳求的url为:http://toolbarqueries.谷歌.com//search?client=navclient-auto&ch=64170410360&ie=UTF-8&oe=UTF-8&features=Rank:FVN&q=info:http%3A//www.ugia.cn,个中的关头局部为ch=64170410360,即CheckSum,不晓得这个是用的甚么算法得出来的。
苦苦搜刮以后,找到以下代码:

在相册系统的开发上,因为采用的是团队分工合作方式,更让我明白了在一个团队之中,团队成员之间的交流沟通的重要性,如果没有很好的沟通交流,成员之间的任务没有分配好。 |
