在程序开发中我们经常要对文件进行编码转换，如果是单个文件转换可以手动处理，但是要对一个文件夹里面上百甚至上千个文件进行编码转换的话手动转换的工作量就很大了，试过网上的几个编码转换软件都不太好用于是自己写了一个程序来处理，原理很简单，取得文件的内容，然后用iconv函数转换为相应的编码后再写入到文件中，注意不能对图片转换，否则会损坏图片文件。- In the program development we often make encoding conversion of the file, if it is a single file conversion can be processed manually, but to a folder inside hundreds or even thousands of file encoding conversion words manually convert the workload is very big, tried several online encoding conversion software is not very good for yourself write a program to process, the principle is very simple, get the contents of the file, and then use the iconv function into a corresponding encoding and then written to the file, not to transfer the image, otherwise it will damage the image file.
