it does not work for copying remote files.

i tried this

<?php

if( isset( $GET['source'] ) & isset( $GET['target'] ) ) {
if ( !copy(  $_GET['source']  , $_GET['target']  ) ) {
	echo "Failed to copy ".$_GET['source'] ." !\n";
	}else {
		echo "ok";
		}

}
else{
echo "syntax: copy.php?source=<..>&target=<..>";
}

?>

but if i try to copy external file ( www.site1.com/file.txt) to the server where the script is run i get error. it does not work

how can i do this ?
thanks

you need to make it "http://www.site1.com/file.txt"

kejo

i already use http://
and it does not work.
what to do now ?

Sorry, I thought that function done it. My bad.

You will need to use file_get_contents()

then you will need to write to a file with... fopen() and fwrite()

I don't think there is an easier way, but i might be wrong.

file system functions

No need to apologize, you were spot on - [man]copy/man works fine; here's a quote from the manual:

Note: As of PHP 4.3.0, both source and dest may be URLs if the "fopen wrappers" have been enabled. See [man]fopen/man for more details.

If it doesn't work, show us the code you tried and exact error message you got.

kejo

ok guys.
this is the code i am using:

<?php

if( isset( $GET['source'] ) & isset( $GET['target'] ) ) {

if ( !copy( $GET['source'] , $GET['target'] ) ) {
echo "Failed to copy ".$_GET['source'] ." !\n";
}else {
echo "ok";
}

}
else{
echo "syntax: copy.php?source=<..>&target=<..>";
}

?>

as you can see i have got to use GET params, and so i point my broswer to:

copy.php?source=http://www.site1.com/file.txt&target=http://www.site2.com/file.txt

but i get error:

Failed to copy http://www.site1.com/file.txt

help me.

What is the value of error_reporting? Is it E_ALL ? If not, set error_reporting to E_ALL (and make sure display_errors is turned On as well) and let us know if PHP spits out any warning messsages, especially something like:

Warning: copy(http://www.site2.com/file.txt) [function.copy]: failed to open stream: HTTP wrapper does not support writeable connections

kejo

i cant do that.
my host forbids me to edit error reporting

If you are using PHP 5.2, [man]error_get_last/man may be an option. If not, perhaps the errors are being logged so you can check the logs instead. Or perhaps track_errors is on and so you can use $php_errormsg.

Well that's stupid. Have you tried using the [man]ini_set/man function to change these two directives, like so:

ini_set('display_errors', 'On');
ini_set('error_reporting', E_ALL);

The reason I want to get error reporting turned on, is because I believe you're receiving a warning such as the one I pasted. Why? Normally, webservers aren't configured to allow the "PUT" operation, which allows you to upload a file across an HTTP connection (different than POSTing the contents of the file - a PUT operation is more like FTP'ing a file to a server, though not exactly the same).

Think about it, it makes sense: Would you want anyone in the world to have the ability to upload files to your webserver? Of course not! Not only could they upload viruses, but they could use up all of your space!

If you have FTP access to the server you wish to upload files to, you might want to consider using the [man]FTP[/man] functions in PHP.

i tried FTP functions but:

Fatal error: Call to undefined function: ftp_connect()

it's not installed 🙁

i will try what you said before.
thanks!

Then I don't know how much luck you're going to have transferring these files.

Why not just make a script on the second server that copies files from the first server?

kejo

lol that's what i want to do!

What it looks like you're doing is having 3 servers:

              Server 1      Server 2
                  \            ^
                   \          /
                    \        /
                     \      /
                      v    /
                     Server 3

The slashes show the direction of data.

Where is this script being run? On server2, where you want the files stored? If so, you shouldn't be specifying a URL, but a location on the local system, e.g. /home/username/www/folder1/file.txt .
