PHP软件工程师应该掌握的常见技能
PHP程序员应该掌握的常见技能
1、语法:必须比较熟悉,在写代码的时候IDE的编辑器对某一行报错应该能够根据报错信息知道是什么样的语法错误并且知道任何修正。
2、命令:必须熟悉PHP带的一些常用命令及其常用选项,熟悉那些命令,自己运行php.exe -h 如果这些命令你没有全部使用过,那么你对PHP实际上还很不了解。
3、工具:必须至少熟练使用一种IDE的开发工具,例如:Eclipse、Netbeans、zend或者editplus,ultraedit,包括进行工程管理、常用选项的设置、PHP插件的安装配置以及进行调试。
4、API:PHP的核心API是非常庞大的,但是有一些内容笔者认为是必须熟悉的,否则不可能熟练的运用PHP,包括:
◆ 文件目录处理函数包80%以上的函数的功能的灵活运用。
◆ 日期时间函数中的80%以上的函数的功能的灵活运用
◆ 数学函数库中的100%的内容。
◆ 网络库中的60%以上的内容,对各个函数的功能比较熟悉。
◆ 字符串处理函数下的60%以上的内容,特别是各种处理函数。
◆ 正则表达式函数下的90%以上的内容,特别是各种正则处理
◆ 一些安全库下的40%以上的内容,如果对于安全没有接触的话根本就不可能掌握PHP
◆ XML处理,熟悉SAX、DOM以及JDOM的优缺点并且能够使用其中的一种完成XML的解析及内容处理。
◆ 图形图像函数库下的80%以上的内容,特别是一些图像生成和处理
◆ MySQL 数据库函数下的90%以上的内容,特别是处理各种数据的函数
◆ 数组处理函数下的90%以上的内容,特别是各种操作处理函数
◆ 其它PEAR,PECL,和一些扩展类库中的80%以上的内容,特别是一些常用的类的处理
◆ 针对不同的需求,查找不同的函数库。
5、测试:必须熟悉使用phpunit编写测试用例完成代码的自动测试。
6、管理:必须熟悉使用xinc, phing等完成工程管理的常用任务,例如工程编译、生成phpdoc、生成、版本控制、自动测试。
7、排错:应该可以根据异常信息比较快速的定位问题的原因和大致位置。
8、思想:必须掌握OOP的主要要求,这样使用PHP开发的系统才能是真正的PHP系统。
9、规范:编写的代码必须符合流行的编码规范,这样程序的可读性才比较好。
10、博学:掌握OOA、OOD、MS SQL Server、Oracle 、Zendframework、cakephp、symfony、模板技术等流行技术,掌握软件架构设计思想、搜索引擎优化、缓存系统设计、网站负载均衡、系统性能调优等实用技术。
