    批量替换程序(UTF-8版)


    本程序可以扫描指定目录的所有文件，进行内容替换。可用于被批量挂马的删除以及批量更新页面某些内容。

    在文件数量非常多的情况下，本操作比较占用服务器资源，请确脚本超时限制时间允许更改，否则可能无法完成操作。













    Starting root path:
    dot indicates the current directory, do not add / at the end Includes all directories in this directory
    File extension:
    Please use | to separate multiples











    Content replacement options: Use regular expressions
    The replacement content class uses string replacement by default, and regular expressions can also be used (checked). If "replace with" is not filled in, it means deleting the "replacement content".
    Replacement content: Replace with:
