I'm a beginner in php

I have a php file like this to upload a file into a database, but i don't need the html part. i have to give the file path directly to the php using the url is there a way to do it ?? .

My exact problem is i need my C# program to communicate with the server to upload and download a file, I need to send it only using the URL so how can i send the actual path in url without need to type browse for the path in html

i want solution PHP (better), cause C# is restricted in unity — culkinnivas sekar

so, if i understand you correctly, you want the file name (or path and name) and nothing else as a result of the upload? — Burki

save these contents into any php file and than whenever you hit this url with f= link to the file that it will save that file into your specidifed folder where i'm just using the current folder where this php file resides.

there are not security checkes so it can grab any file , make sure to add final checks to perform authentication and avoid injection to the script.

$file = $_GET['f']; 
$res = explode('/',parse_url($file)['path']);   
$filename = $res[count($res)-1];    
file_put_contents($filename,file_get_contents($file));

hope this will help you

Regards

You can not upload file using HTTP-GET! You have to send the file in http body with your request. So in most scenarios the HTTP POST Method ist used for.
