对自己当前PHP知识掌握情况的一个总结

1、可以在windows下简单搭架PHP的开发环境，这个是最基本的，只有环境搭配好了，才可能谈得上去学习和开发。这里主要是指appach+php+mysql环境的搭配，对新手来说，通常采用的是wamp安装包。到现在，我也依然是采用wamp安装包进行环境搭配，不知道独立安装会不会更好呢？以后再作探讨。至于iis+php环境的搭配也略懂一点，不过不会去作深入研究，因为appach+php+myql是最好的搭配了。另外需要深入学习的是在linux系统下进行php环境的搭配，LAMP才是王道(L指linux,A指appach,M指mysql,P指php(或者Perl或者Python).

2、熟练掌握基本的语法。环境搭配好后当然是对基本的语法的学习了，我这里所说的基本语法是指怎么去书写php，也就是怎么使用php,php的标记风格有哪些，php的数据类型有哪些，php的注释方式，常用的流程控制语句(if,while,for,switch,foreach等)，php如何与数据库(常用的mysql)进行连接。对我来说，可以开发一个简单的留言板，也就算对php基本语法基本掌握了。

3、熟练掌握常用的函数。函数可以帮我们更快速地开发，可以说掌握越的函数越多，我们的开发工作也变得越简单,而且使用系统内置的函数执行效率也比较高。php系统内置的函数很多，当然是不可能每一个都记住啦，所以对一些不是常用的函数有大致的印象就可以了，大概知道有这样的一个函数是用来干什么的，当我们需要用到的时候去百度一下把它找出来。

4、能解决基本的编码问题。新手来说，可能很容易遇到编码问题，也就是出现乱码，通常出现乱码是因为编码不统一。我采取对策是全部统一采用utf-8编码，utf-8编码是国际编码，所以utf-8编码应该是个趋势吧。我是这样设置的，php文件前都加一句header("Content-type:text/html;charset=utf-8);强制页面以utf-8编码显示，html文件在<head></head>标记间加了一句<meta http-equiv="Content-Type" content="text/html; charset=utf-8">;用到数据库时还要加一句mysql_query("set names utf8");至于数据库创建那里好像不用utf-8编码也可以，不过最好还是用。这样基本上不会出现乱码的情况，至少我还没遇到过。

5、模板引擎smarty.因为用过smarty进行了一次新闻系统的开发，所以对它用法基本上还是比较了解的。

6、对在线编辑器有一定的了解，这里我使用的是fckeditor,能够对fckeditor进行简单配置，去除不必要的功能，实现文件上传。

7、面向对象跟正则表达式。面向对象更重要的是掌握它的思想，这个是个大趋势来的。正则表达式，这个也是要掌握的重点。不过自己对这两个的接触还只算皮毛，实际应用得还是比较少，以后开发的时候会多加注意。

上面大致是我对php的一个掌握情况，接下来会大致朝两个方向学习，第一，常用的开发框架（目前正在学thinkphp开发框架)；第二，对linux系统的学习。

      Another thing I have really noticed is for many people, a bad credit score is the result of circumstances above their control. As an example they may are already saddled with an illness so they have high bills for collections. It could be due to a employment loss or maybe the inability to work. Sometimes breakup can truly send the financial circumstances in the undesired direction. Many thanks sharing your thinking on this website.

      billiga webbhotell kan guida dig för att välja ett billigt och bra webbhotell. Väldigt många webbhotell har en hel del att erbjuda medans vissa tyvärr använder oärlig reklam för att locka så många kunder som möjligt, som bidrar med problem för kunderna.

      This is not related, but most of you probably don't know this, precisely what the heck. Eat moderate portions.

Do you realize the recommended serving of cooked meat is 3 ounces, similar in space to some deck of charge cards? A medium part of fruit is 1 serving and a cup of pasta equals 2 servings. A pint of ice cream contains 4 servings.
