    php程序员需要掌握的五个概念:

    我们从书本上学到的一些php理论知识和实际的程序设计还是有一些区别的,真正的知识和经验要从实际的开发中获得.每个php程序员在开始开发web应用程序之前,都应该了解下面的五件事:

    1. 模板引擎

    如果您使用的不是一个框架来执行一个具体的设计模式,那么您想要使用的是模板引擎.不论你是自己创建或是使用现有的模板(如 Smarty),模板引擎都会使你的逻辑代码从HTML页面中独立出来(以及相关的CSS / js /等). 这大大的简化了你的代码,使整个程序的修改变得快速简单,也使非开发者更容易修改你的程序.

    2. php框架

    框架可以说是php开发中的一个最重要的问题. 用php开发web应用程序时有很多方法,有很多开源的框架可以使用,可以帮助快速的开发,保持更高的一致性和有效性. 其中比较好的框架包括cakephp ,Symfony和CodeIgniter .很多框架还按照MVC设计模式 ,如果你在这个模式下工作过,那你一定会很熟悉.过一段时间,你甚至可以根据自己的需要来创建框架.

    3. 代码重用

    正如我先前提过的,php是所用语言中代码重用性最好的.从多中小的文档到整个数据库类,php开发者需要的时候可以随意的选择重用现有的代码.其实,你几乎可以不用编写一行代码就能建立起整个应用程序.

    4. IRC 是令人愉快的事

    当你有个复杂的问题不能解决的时候,可以到IRC上.php非官方的支持频道,很多经验丰富的开发者陶醉其中.你需要一个IRC客户端,如果你用的Firefox,ChatZilla是一个很好的插件,当你需要帮助时,以irc://irc.freenode.net/php做为头部粘贴你的代码.张贴您的问题,并耐心等待;某种热心人(或多个)会给你答案.当你得到答案后,考虑一下其他需要帮助人的问题.对于php庞大的函数库来说,没有人是泰斗;在IRC上,汇集所有人的知识就可以解决任何问题

    5. 不重新开发现有的东西

    很明显的一件事,只有少数的php开发者知道php本身有很多可用之处.忘记新的图书馆,或复杂的代码例程-先看看PHP手册. 例如,你们有没有听过number_format(), parse_url(), wordwrap()或bbcode_parse()?看一下整个函数参考 ,选择一个类别,浏览一下,您一定会有所发现.
