For mysqli, adding:

MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT

to real_connect() solved my instance of this issue.

Example (replace host, user, password and database as needed):

$db_connection->real_connect('ip address or host', 'user', 'password', 'database', 3306, NULL, MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT);

Full php mysqli SSL connection script:

// check if openssl is enabled on server
if(!extension_loaded('openssl')) {
    throw new Exception('This app needs the Open SSL PHP extension and it is missing.');
}

// start connection
$db_connection = mysqli_init(); 

// set ssl config (update with your certs location)
$db_connection->ssl_set('/etc/my.cnf.d/certs/client-key.pem','/etc/my.cnf.d/certs/client-cert.pem', '/etc/my.cnf.d/certs/ca-cert.pem', NULL, NULL); 

// connect (update with your host, db and credentials)
$db_connection->real_connect('ip address or host', 'user', 'password', 'database', 3306, NULL, MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT);
