How Can I Implement SFTP Functionality in PHP?

How to Implement SFTP Functionality in PHP

PHP does not natively support SFTP (SSH File Transfer Protocol). However, you can leverage PHP's stream wrappers feature to access SFTP functionality using the ssh2 stream wrapper.

Using the ssh2.sftp:// Stream Wrapper

PHP provides ssh2 stream wrappers that allow you to interact with SFTP servers using functions that support stream wrappers. The syntax is as follows:

file_get_contents('ssh2.sftp://user:password@host:port/path/to/filename');

Replace "user", "password", "host", "port", and "path/to/filename" with the appropriate values.

Using the ssh2 Extension

If you also have the ssh2 extension installed, you can use a more robust approach:

$connection = ssh2_connect('host', port);
ssh2_auth_password($connection, 'username', 'password');
$sftp = ssh2_sftp($connection);
$stream = fopen("ssh2.sftp://$sftp/path/to/file", 'r');
