php 遍历目录文件编码转换
遍历当前目录及子目录，把所有的文件转换编码到UTF-8，代码如下:
- //php iconv.php
- //exec it on root dir
- $path = dirname(__FILE__);
- tree($path);
- function encodeFiles($fileName)
- {
- // echo $fileName;
- if (file_exists($fileName)) {
- // Read in the contents
- $res = file_get_contents($fileName);
- $i = pathinfo($fileName);
- if(!in_array($i['extension'],array('js','css','php','html','htm'))){
- return ;
- }
- // Just display on the screen the file being modified
- echo $fileName . "---form---";
- // Convert the contents
- echo $encode = mb_detect_encoding()($res, array("ASCII", "UTF-8", "GB2312", "GBK"));
- echo "---to---UTF-8!\n";
- $res = iconv($encode, "UTF-8", $res);
- // Write back out to the same file
- file_put_contents($fileName, $res);
- } //
- }
- function tree($directory)
- {
- $mydir = dir($directory);
- while ($file = $mydir->read()) {
- if ((is_dir("$directory/$file")) AND ($file != ".") AND ($file != "..")) {
- tree("$directory/$file");
- } else {
- $file ="$directory/$file";
- // echo "<li>$file</li>\n";
- if(is_file($file)){
- encodeFiles($file);
- }
- }
- }
- }
