最近,自己利用放假时间学PHP,可能大家都不知道PHP是什么呢?PHP是一种网页嵌入式语言,就同ASP,JSP一样,这应该是编程中最容易学习的语言。前几年自己在华师上夜大的时候,唯一学习的编程语言是C++。现在这个PHP编程很多地方与C++类似,所以被称为C++ --(即C加加减减)很有趣的称呼,哈哈!why?因为它没C++一样要使用指针比较复杂的结构类型罗!
     还有更有趣的称呼,在电脑界把php称为明灯(LAMP)WHY?原因在于php只是一种编程语言,它需要特定的环境才能运行,所以这个环境就叫做LAMP了,其实是包括四样东西(Liunx,Apache,Mysql,Php),liunx,就是同微软、window一样的操作系统,Apache就是服务器如同windows中的IIS(internet information server),Mysql就是数据库,同Access,Sqlserver,Oracle一样,因为现在的网页很多都是动态网页(这个动态不是单指画面的动态,更是强调动态地管理),PHP当然已经介绍过了是scrīpt language. [2008-2-9]
    我现在学习的是PHP当然要介绍它多一点啦!php其实就同普通我们上网看到的网页语言没什么区别,普通的网页是HTML语言,十分简单的语言,我在读大学的时候已经掌握了,但是要经常记住一些tags是很不容易,但是你学习网页必须要懂得这样,而PHP就是把语句嵌入在其中间,通过PHP解释器对其进行编译,这样就可以得出网页效果的,虽然学习这个容易要花一定的时间,但这种语言是方便我们平时的网页编辑,通过语句的编写这样可以减免对网页的重复制作,说真的是提高工作效率,很棒的!
     当然学习语言就像我们平时学习的english一样,要学习语法,句型等,当然没有英语语句这么多句型了,在编程语言中主要有三种结构(顺序、选择、循环结构),通过三种的结构的组合就可以编写网页和程序了。但编程语言更像的数学这科,因为有很多函数,但往往很多函数就是自己最容易不记得的。但没办法了,只有自己多点用吧!我最近在最具权威的www.php.net网站上下载了有关PHP的语法手册,这本手册不错,很通俗易懂是学习php语言的首选材料。另一个最具权威的网站是www.zend.net 这个网站,从资料中得知zend其实是两个人的名字合写在一起,这两个人就是当初php的发明者,现在成立了zend公司,听说这个公司也准备上市了,市场潜力也是很巨大的,最近IBM也就PHP的应用在其网站提供了相关的资料介绍。

     目前的网页变成语言都离不开与数据库的支持,这是一种很有用的技术支持,以前的网页都处于静态,很多资料都不能保存,现在数据库可以通过其严密的关系结构,使网页更具信息的系统性和安全性。目前流行的数据库很多,我自己也不清楚那些数据库软件好用,自己用过的有SQLSERVER,MYSQL,至于IBM强烈推荐的DB2 V9则没用过。[2008-2-10]

Here are the different ways to add elements to an array: Use square brackets [] In PHP, the way to add elements to the end of an array is to use square brackets []. This syntax only works in cases where we want to add only a single element. The following is the syntax: $array[] = value; Example
