Client

Example: Uploading

use peer\ftp\{FtpConnection, FtpTransfer};
use io\File;

$c= (new FtpConnection('ftp://user:pass@example.com/'))->connect();

// Upload logo.png to the connection's root directory
$c->rootDir()->file('logo.png')->uploadFrom(new File('logo.png'));

// Upload from a stream using ASCII mode
$c->rootDir()->file('README.md')->uploadFrom(
  new MemoryInputStream('Read me first!'),
  FtpTransfer::ASCII
);

$c->close();

Example: Listing

use peer\ftp\FtpConnection;

$c= (new FtpConnection('ftp://user:pass@example.com/'))->connect();

// List root directory's contents
foreach ($c->rootDir()->entries() as $entry) {
  Console::writeLine('- ', $entry);
}

$c->close();
