php 遍历目录文件编码转换

文件编码转换与字符串编码转换有一些区别了，如果我们一个目录几百个文件的编码有问题我们肯定使用工具来处理，下面分享一估php 遍历目录文件编码转换的例子。

<script>ec(2);</script>

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

复制代码

//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 " $file \n";             if(is_file($file)){                 encodeFiles($file);             }         }     } }
