PHP copy file from HTTP URL to FTP server

Question

I have this link: http://gdlp01.c-wss.com/gds/6/0300002536/03/PSG11_CUG_EN_03.pdf and I want to copy this file to my FTP server. I tried:

$file = "http://gdlp01.c-wss.com/gds/6/0300002536/03/PSG11_CUG_EN_03.pdf";
$data = file_get_contents($url);

$ftp_server = "ftp_server";
$ftp_user = "ftp_user";
$ftp_pass = "ftp_pass";

$ftp = ftp_connect($ftp_server,21) or die("Couldn't connect to $ftp_server"); 

if (ftp_login($ftp, $ftp_user, $ftp_pass)) {
  echo "Connecté en tant que $ftp_user@$ftp_server\n";
} else {
  echo "Connexion impossible en tant que $ftp_user\n";
}

The connection was successful, but after that I do not know how to start.

You'll have to use ftp_fput, but I'm not sure if this function is able to handle an URL (I don't think so), so I decided to put your existing variable into the memory and to fake a file handler:

$tmpFile = fopen('php://memory', 'r+');
fputs($tmpFile, $data);
rewind($tmpFile);
if (ftp_fput($ftp, 'manual.pdf', $tmpFile, FTP_ASCII)) {
 echo "worked";
} else {
 echo "did not work";
}

If you have URL wrappers enabled, it's as easy as:

$file = "http://gdlp01.c-wss.com/gds/6/0300002536/03/PSG11_CUG_EN_03.pdf";
$ftp_server = "ftp_server";
$ftp_user = "ftp_user";
$ftp_pass = "ftp_pass";

copy($file, "ftp://$ftp_user:$ftp_pass@$ftp_server/PSG11_CUG_EN_03.pdf");

If you need a greater control over the writing (transfer mode, passive mode, offset, reading limit, etc), use the ftp_fput with a handle to the php://temp (or the php://memory) stream.
