PHP批量修改静态html文件编码的例子

<?php

foreach(glob($dir . '*.htm*') as $html)

    //读取文件
    $fp = fopen($html, 'a+');
    $html_string = fread($fp, filesize($html));
   
    //转码操作
    $html_string = str_replace('charset=gb2312', 'charset=UTF-8', $html_string);
   
    $file_code = mb_detect_encoding()($html_string, array('UTF-8','GBK','LATIN1','BIG5'));
   
    if($file_code = 'CP936')
    {
        $html_string = mb_convert_encoding($html_string ,'utf-8' , 'gbk');
    }
   
    //获取文件名
    $slice = explode('/', $html);
    $file_name = end($slice);
   
    //移到新文件
    file_put_contents($move_to . $file_name, $html_string);
