使用URL上传文件是否应允许FTP url？

Question

In my project we are uploading files to server, and allowing URLs also. Before using those URLs we validate URL using following validation function:

public function checkUrl( $strUrl ) {
    return ( true == preg_match( '/^(http|https|ftp):\/\/(([A-Z0-9][A-Z0-9_-]*)(\.[A-Z0-9][A-Z0-9_-]*)+)(:(\d+))?/i', $strUrl ) ) ? true : false;
}

now in this we have allowed ftp also.

I just want to know, is it a good idea to allow FTP URLs in file upload?

Answer 1

Personally I avoid this (w. no particular reason). But why not ;)
