默认 文件批量转换器（从ansi 到 Utf-8） --转
文件批量转换器（从ANSI 到 UTF-8）（PHP）
其中几个函数很好用，我花了一天时间
直接创建多层目录mymkdir($dirname)，
批处理目录下的文件function listDirTree( $dirName = null ,$callFunction) 可自定义处理函数。
如：
PHP 代码:
代码:
$callFunc="backupFile(\"$backupPath\",\$file,\$filePath,\$dirName);";
listDirTree($operateDir,$callFunc);

将文本中 x=y
u=a
提取为数组的函数
function myExplode($originalStr,$firstTag,$secondTag)
将文件转换为utf-8编码的函数。function gb2utf8($file,$filePath)
判断文件是否为utf-8编码的函数 function utf8_probability(&$rawtextstr)



PHP 代码:
代码:
<?php
//header('Content-Type: text/html; charset=utf-8');
$fname=str_replace("\\\\","/",$_POST['fname']);
$encode=$_POST['encode'];
$changeType=$_POST['changetype'];
