Download file using curl in php

You would need to feed CURLOPT_URL the full URL to the file. Also if you want to download a file you might want to save it somewhere.

Working example:

$curl = curl_init();
$file = fopen("ls-lR.gz", 'w');
curl_setopt($curl, CURLOPT_URL, "ftp://ftp.sunet.se/ls-lR.gz"); #input
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FILE, $file); #output
curl_setopt($curl, CURLOPT_USERPWD, "$_FTP[username]:$_FTP[password]");
curl_exec($curl);
curl_close($curl);
fclose($file);

I used the ftp_* functions for ftp, in place of curl, because curl 
tried to change directories, but its not allowed on this ftp server, so 
the code i used is;



$local_file = 'output.rar';
$server_file = '/somedir/1/bar/foo/somearchive.rar';
$ftp_user_name='anonymous';
$ftp_user_pass='mozilla@example.com';
$ftp_server='server.host';
// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

/* uncomment if you need to change directories
if (ftp_chdir($conn_id, "<directory>")) {
    echo "Current directory is now: " . ftp_pwd($conn_id) . "\n";
} else { 
    echo "Couldn't change directory\n";
}
*/

// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
} else {
    echo "There was a problem\n";
}

// close the connection
ftp_close($conn_id);
It works !!
