What steps should be followed to generate and use a new SSH key pair in PHP for authentication?

To generate and use a new SSH key pair in PHP for authentication, you can use the `ssh-keygen` command to generate the key pair and then use the generated private key for authentication in your PHP code. You can use the `ssh2_auth_pubkey_file` function in PHP to authenticate using the generated SSH key pair. 

// Generate SSH key pair using shell command
shell_exec('ssh-keygen -t rsa -b 4096 -f /path/to/private_key');

// Authenticate using the generated SSH key pair
$connection = ssh2_connect('example.com', 22);
ssh2_auth_pubkey_file($connection, 'username', '/path/to/public_key', '/path/to/private_key');
