PHP压缩目录成ZIP

前言

最近需要压缩整个目录为ZIP，网上找到的代码测试了几份都有存在的BUG，最终找到一份强大的博文

在linux奔跑时，发现几处异常

• 抛出rename()方法报错，仔细一看发现转换时候用到了\\,而linux下应该为/,兼容两种环境于是直接改写为DIRECTORY_SEPARATOR，并将四个方法改写为类，贴出来以便以后使用。
• 在处理目录和文件的时候将GBK转为UTF-8，还原的时候将UTF-8转为GBK，当目录或者文件编码不为GBK的时候会导致异常，因此修改了转码时候的代码：记住原文件或目录的字符编码，在压缩结束后还原最初的编码。
  再次感谢原博主power124932811的贡献。

不多BB，上代码

正确食用

(new MakeZip())->zip('目录绝对地址'，'生成的文件名绝对地址') #成功返回true，有报错返回false，异常捕获在$e中自行测试
