I was wondering the same thing. so far, I am just fopen()'ing the file and doing read/write to the local file. Like so:

<pre>
if (!($fp = fopen($srcfile,"r"))) die("Could not open src");
if (!($fp2 = fopen($file,"w"))) die("Could not open dest");

while ($contents = fread( $fp, 4096 )) {
fwrite( $fp2, $contents, strlen($contents) );
}
fclose($fp);
fclose($fp2);

</pre>

Just to be a little more clear on the above... the $srcfile is a URL (in my case, it's "http://www.slashdot.org/slashdot.xml" but it could be an FTP or any other proper URL)

Here is some useful notes on my experience with copy
<pre>
$path ="../../images/press";
// copying image
if ($image_type == "image/pjpeg") {
copy($image,$path.$image.".jpg");
$name = $image;
$name.=".jpg";
}
</pre>

Manipulate as needed :)

To serve a file to a client from the server you can do this: (This also enables dynamic file content just by altering what is echo'd out)
<pre>
<?
$fp = fopen("file.x","r");
$buff = fread($fp,1000000);
Header("Content-Type: application/x-octet-stream");
// you can put the header file-length here but I never use it!
Header("Content-Disposition: attachment; filename=DOWNLOADEDFILENAMEHERE"); echo $buff;
</pre>
this will trigger the download action.

To people asking how to copy files to and from the server and client:

Look at the PHP documentation under features/handling files uploads.
http://www.php.net/manual/features.file-upload.php

There you will find how to get a file from the client to the server via HTTP and a web browser.

The other direction (Server to client) has been addressed before, but look in the section on readfile:
http://www.php.net/manual/function.readfile.php
It will tell you the easy way.
