Opening file from webserver

Aytolucus

Well i'm trying to make a script that opens a .txt file from a webserver, writes some stuff in it and closes it. Note that the script.php file is in the same folder wher file.txt is. Here is my code:

<?php

$file = fopen('http://freehost.stuff.gr/lite/file.txt', 'k');
fwrite($file, 'Text');
fclose($file);

?>

Unfortunately i get the following compilation error:

Warning: fopen(http://freehost.stuff.gr/lite/file.txt): failed to open stream: HTTP wrapper does not support writeable connections. in /home/freehost/lite/script.php on line 3

Warning: fwrite(): supplied argument is not a valid stream resource in /home/freehost/lite/script.php on line 4

Warning: fclose(): supplied argument is not a valid stream resource in /home/freehost/lite/script.php on line 5

What is wrong? What should i do to make my code work?

You can't open a remote file for writing. If it's local, use the actual path to the file, not the web address.

Hi,

That warning is saying that you need to configure PHP to allow fopen to be able to open files across the web (ie filepaths starting with [url]http://[/url]).

But you don't need that ...

<?php 

$file = fopen('file.txt', 'w'); // What does 'k' do?
fwrite($file, 'Text'); 
fclose($file); 

?>

More generally, you need to use the full path to the file if it's in a different folder ... $_SERVER['DOCUMENT_ROOT'] often comes in handy at this point 🙂

What you mean you can't open a remote file for writing? There is no way?

Thanks Raul 🙂

Not using php's file methods. You'd have to download, modify, and upload.

Imagine you could just edit any remote file. Then anyone with PHP installed could open up files on your webserver and edit them.

LordShryku, what paulnaj mentoned worked perfectly. The file can now be opened and successfully edited :rolleyes:

That's because you are dealing with a local file.

Using:
http://freehost.stuff.gr/lite/file.txt
indicates that you wish to open file.txt on freehost.stuff.gr via HTTP.

Using:
file.txt
indicates that you wish to open file.txt on the local host, via the filesystem.
