phpSFTP

PHP SFTP class that supports both implicit and explicit SFTP

I created this class due to the need to support both implicit and explicit SFTP. Implicit SFTP connections are handled via cURL while explicit connections are handled via the standard PHP ftp_ functions. Only the functions that I needed at the time are supported however others could easily be added.

Instructions

• Download the class, no need for any fancy dependency managers or whatnot.
• Include it in your code

require_once 'include/phpSFTP.php';

Usage

• Instantiate your object. This will also validate your connection works.

$implicit = true;
try {
    $ftp = new phpSFTP($hostname, $username, $password, $port, $implicit);
} catch(Exception $e) {
    echo "Failed connecting to $identifier via SFTP.  " . $e->getMessage()";
    exit;
}

• List a directory

$list = $ftp->dir('/');
foreach($list as $file) {
    echo "Filename: $file\n";
}

• Download a file

if($ftp->get("/tmp/local_file.txt", "/xyz/remote_file.txt")) {
    echo "File downloaded as /tmp/local_file.txt";
} else {
    echo "File downloaded failed";
}

• Upload a file

if($ftp->put("/tmp/local_file.txt", "/xyz/remote_file.txt")) {
    echo "File uploaded as /xyz/remote_file.txt";
} else {
    echo "File upload failed";
}

• Rename a file

if($ftp->rename("/xyz/remote_file.txt", "/xyz/remote_file_renamed.txt")) {
    echo "File /xyz/remote_file.txt as /xyz/remote_file_renamed.txt";
} else {
    echo "File rename failed";
}

• Delete a file

if($ftp->delete("/xyz/remote_file_renamed.txt")) {
    echo "File /xyz/remote_file_renamed.txt deleted";
} else {
    echo "File delete failed";
}

• Close the connection

$ftp->close();
