提供md5文件的php脚本

Question

I need some help. : D

I want to create a page where you can upload one or more files after it is uploaded they get the md5 of the file

it must work with files that are on their computer but also files that are already on another server

so if they form a paste in the link text and click on submit, they also get the md5

I hope someone can help and get me a script ore something

Answer 1

You can't get the md5 of a file from user's computer, but you can get the md5 of a file stored in your server with the md5_file() function.

Usage: md5_file('path/to/file/file.ext');
