PHP转换文件夹下所有文件编码

PHP转换文件夹下所有文件的编码 适合发布网站的其他编码版本 比如你有一个GBK版本 你想有一个UTF8版本 或者你只有GBK的源码 你想二次开发 但是你不想改变IDE的编码方式 你可以用这个程序将其批量转化为UTF8:

代码如下:

 


/**
 * 把一个文件夹里的文件全部转码 只能转一次 否则全部变乱码
 * @param string $filename
 */
function iconv_file($filename,$input_encoding='gbk',$output_encoding='utf-8')
{
	if(file_exists($filename))
	{
		if(is_dir($filename))
		{
			foreach (glob("$filename/*") as $key=>$value)
			{
				iconv_file($value);
			}
		}
		else 
		{
			$contents_before = file_get_contents($filename);
			/*$encoding = mb_detect_encoding($contents_before,array('CP936','ASCII','GBK','GB2312','UTF-8'));
			echo $encoding;
			if($encoding=='UTF-8')  mb_detect_encoding函数不工作
			{
				return;
			}*/
			$contents_after = iconv($input_encoding,$output_encoding,$contents_before);
			file_put_contents($filename, $contents_after);
		}
	}
	else 
	{
		echo '参数错误';
		return false;
	}
}
iconv_file('./test');
Copy after login
