    I wrote support ssl mysqli you don't need change anymore mysqli connect exchange to your own mysqli . Overwrite __construct mysqli with support ssl can be like that:
    <?php class myssl_mysqli extends \mysqli {
    public function     __construct($db_host, $db_user, $db_pass, $db_name, $port, $persistent = true, $ssl = false, $certpublic = "") {
    if(    $ssl) {
    parent::init();
    parent::options(MYSQLI_OPT_SSL_VERIFY_SERVER_CERT, false);
    parent::ssl_set(NULL, NULL, $certpublic, NULL, NULL);
    parent::real_connect(($persistent ? 'p:' : '') . $db_host, $db_user, $db_pass, $db_name, $port, '', MYSQLI_CLIENT_SSL | MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT );
    } else {
    parent::__construct($db_host, $db_user, $db_pass, $db_name, $port);
    }
    }
    $db = new myssl_mysqli('localhost','user', 'pass','db', '3306', true, true, '/home/mypublicowncert.pem');
    ?>
    in this example i off the verificate cert by authority ssl, due it own cery created

    Correct way to connect db

    <?php

    mysqli_report    (MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
    $mysqli = new mysqli("127.0.0.1", "db_user", "db_pass", "db_name",3306);

    $result = $mysqli->query("SELECT somefield1, somefield2 FROM sometable ORDER BY ID LIMIT 3");

    /* Close the connection as soon as it becomes unnecessary */
    $mysqli->close();

    foreach (    $result as $row) {
    /* Processing data received from the database */
    echo var_dump ($row);
    }
