Web 2.0 时代PHP能走的更远吗

随着所谓WEB2.0时代来临,程序员从来没有时代象今天那样受人注意,很多程序员对于语言的争论也从来没有象今天这样剧烈,JAVA、C++、PHP、ASP等等,最近又出来一个Ruby,加上Python。无数的FANS在中间进行争论不休,也就是在网路上,如果是在现实生活中,大概会象《倚天屠龙记》里描述的那样,会决战光明顶来定一个胜负,或者说定出天下第一大门派。而现在定出谁是天下第一大其实很方便,看一下哪个语言旗下的弟子人数即可。而现在最流行的统计方式,就是Google了,看看Google的搜索结果,基本就能判断出其在市面上的网站的使用情况
◆约有5,760,000,000项符合 php 的查询结果
◆约有3,070,000,000项符合asp的查询结果
◆约有976,000,000项符合java的查询结果
◆约有327,000,000项符合perl的查询结果
◆约有238,000,000项符合python的查询结果
◆约有225,000,000项符合c++的查询结果
◆约有176,000,000项符合ruby的查询结果

这段时间葛优的光脑袋频繁曝光,总是喋喋不休的告诉俺们一个道理——用的人多的卡就是好卡。而如果套用这个光头明星的话,那就是,我,相信群众,从上面查询的结果大家可以看到,人民群众是很爱戴PHP的。

但如果你去问互联网的一些资深开发人员,PHP、ASP与Java,他们之间谁更好?一般来说,这个人都会告诉你,ASP就不用想啦,微软出的垃圾,PHP和Java是不错的选择,Java适合做大项目,PHP适合做一些短平快的东西。如果你还继续问,这个高手还没有失去耐心的情况下,他大体都会说,你看世界上最大的互动平台eBAY,就是用JAVA写的,中国最大的社区CHINAREN校友录也是JAVA,而很多小的网站,初期都是PHP,后来各种原因都必须改到JAVA上面去。这种感觉就是像说,如果你想学武功以便出去砍人,或者说在江湖扬名立万,那么行军拳你就不用练啦,这个东西是政府拿出来强身键体的,五虎断门刀这个东西你用来对付一般的流氓是绰绰有余,但是碰到绝顶高手你就歇了。而Java有点象太极拳,当今武林最大的门派之一SUN的首推武功,是对负高手的不二选择,于是很多人就认定:PHP是低等武功,练到最好的结果也就是给赌场看看场子,只有练就Java才能做武林盟主。

俺和很多公司的技术经理聊的时候,经理们说很多人都有这种心理,他是使用Java的,而你如果让他写PHP,,很多人会有一种受到侮辱的感觉,不是觉得经理不重视他,就是在想自己什么时候得罪了经理,竟然被发配到PHP这种偏远的小地方去了。越是大公司,PHP的项目越难开展起来,这个让很多技术老大们很是郁闷,但也很是奇怪。所以,下面,咱们一起分析一下形成这种被人民群众认可,却不被很多开发人员看好的语言——PHP。

PHP 进入中国是98,99年,进入的时候,初期应用的典型是Chinaren校友录,还有很多的互动应用,它以开发方便,容错性好,迅速成为很多网站的选择。到了00,01年,互联网泡沫的时候,很多都是PHP完成对网站的开发,它的流行有以下几个原因:

兼容C的语法,容易掌握

就这一点来说,它保证了开发人员的稳定来源,基本上说,每个学计算机的人员,没有不学习C 语言的,所以都能在一到两周左右快掌握这个新的语言,然后经过简单的指导,就能开始初期的开发工作。单从程序本身的开发而言,写了三年以上的程序员,和开发了半年以上的PHP程序员差别不是太大。

运行的快速

在网路上面,速度是很重要的问题,这一点来说及时是对PHP非常不屑的人也不得不承认PHP得运行速度还是比较令人满意的,只不过由于没有很实际的数据,只是很多人感觉,所以这一点来说,没有非常有力的证据证明。

非常强的容错,很好的鲁棒性能

很多写PHP的人员应该有这个感觉,举个例子,你申请一个PHP中的变量,做数字也行,做数组也行,做字符串也可以。我有时候都在想,这么随意的风格,他是如何保证效率的,只能说写这个语言编译器的人实在太不可思议了。
