兴趣可能会慢慢消亡,所以适当培养兴趣会激发自己无线的乐趣,有了乐趣,编程有啥难的。 最后介绍一个代码出错,但是老找不到错误方法,就是 go to wc (囧),出去换换气没准回来就找到错误啦。 开发工具也会慢慢的更专业,每个公司的可能不一样,但是zend studio是个大伙都会用的。 最后介绍一个代码出错,但是老找不到错误方法,就是 go to wc (囧),出去换换气没准回来就找到错误啦。 最后祝愿,php会给你带来快乐的同时 你也会给他带来快乐。 再就是混迹于论坛啦,咱们的phpchina的论坛就很强大,提出的问题一般都是有达人去解答的,以前的帖子也要多看看也能学到不少前辈们的经验。别的不错的论坛例如php100,javaeye也是很不错的。 这些中手常用的知识,当你把我说的这些关键字都可以熟练运用的时候,你可以选择自己 这些都是最基本最常用功能,我们这些菜鸟在系统学习后,可以先对这些功能深入研究。 使用 jquery 等js框架的时候,要随时注意浏览器的更新情况,不然很容易发生框架不能使用。 多看优秀程序员编写的代码,仔细理解他们解决问题的方法,对自身有很大的帮助。 基础有没有对学习php没有太大区别,关键是兴趣。 首先我是坚决反对新手上来就用框架的,因为对底层的东西一点都不了解,造成知识上的真空,会对以后的发展不利。我的观点上手了解下框架就好,代码还是手写。当然啦如果是位别的编程语言的高手的话,这个就另当别论啦。 微软最近出的新字体“微软雅黑”,虽然是挺漂亮的,不过firefox支持的不是很好,所以能少用还是少用的好。 我还是强烈建议自己搭建php环境。因为在搭建的过程中你会遇到一些问题,通过搜索或是看php手册解决问题后,你会更加深刻的理解它们的工作原理,了解到php配置文件中的一些选项设置。 开发工具也会慢慢的更专业,每个公司的可能不一样,但是zend studio是个大伙都会用的。 多看优秀程序员编写的代码,仔细理解他们解决问题的方法,对自身有很大的帮助。 这些中手常用的知识,当你把我说的这些关键字都可以熟练运用的时候,你可以选择自己 如果你可以写完像留言板这样的程序,那么你可以去一些别人的代码了, 说php的话,首先得提一下数组,开始的时候我是最烦数组的,总是被弄的晕头转向,不过后来呢,我觉得数组里php里最强大的存储方法,所以建议新手们要学好数组。 写的比较杂,因为我也是个新手,不当至于大家多多指正。
