php经过长时间的发展，很多用户都很了解php了，这里我发表一下个人理解php数组排序，和大家讨论讨论。php是一种易于学习和使用的服务器端脚本语言。只需要很少的编程知识你就能使用php建立一个真正交互的web站点。本教程并不想让你完全了解这种语言，只是能使你尽快加入开发动态web站点的行列。我假定你有一些html（或者html编辑器）的基本知识和一些编程思想。

PHP网页文件被当作一般HTML网页文件来处理并且在编辑时你可以用编辑HTML的常规方法编写PHP。 PHP代表：超文本预处理器（PHP: Hypertext Preprocessor）。PHP是完全免费的，不用花钱，你可以从PHP官方站点(http://www.php.net)自由下载。PHP遵守GNU公共许可（GPL)，在这一许可下诞生了许多流行的软件诸如Linux和Emacs。你可以不受限制的获得源码，甚至可以从中加进你自己需要的特色。PHP在大多数Unix平台，GUN/Linux和微软Windows平台上均可以运行。说了这么多，下面我们就讲解一下关于PHP数组排序。
