Am trying to insert data from a php form using OOPs in PHP.
Am getting the error that ->

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"username','email','password") VALUES ("Bob','','$1$RL4.GJ4.$FX4D' at line 1

Am failing in this as i am new to oops with php.
Here's the code for that handles the class of database in php register.class.php ->

class DataBase {
    public $connection;
    private $hostName;
    private $userName;
    private $pasWord;
    private $db;

    public function connect($host, $user, $pass, $dtb) {
        $this->hostName = $host;
        $this->userName = $user;
        $this->password = $pass;
        $this->db   = $dtb;

        return $this->connection = mysqli_connect($host, $user, $pass, $dtb)
                                    or die('Could Not Connect.');

    public function insert($fields, $data, $table) {
        try {
            $queryFields = implode("','", $fields);
            $queryValues = implode("','", $data);

            $insert = 'INSERT INTO '.$table.'("'.$queryFields.'") VALUES ("'.$queryValues.'")';

            if (mysqli_query($this->connection, $insert)) {
                return true;
            } else {
        } catch (Exception $ex) {
            echo "Some Exception Occured " . $ex;

Here's the code of the form register.php ->

        include 'register.class.php';

        $con = new DataBase();

        $con->connect('localhost', 'root', '', 'test');

        if (isset($_POST['submit'])) {
            $uName = $_POST['userName'];
            $email = $_POST['email'];

            $pass = $_POST['passWord'];
            $passHash = crypt($pass);

            $fields = array('username', 'email', 'password');
            $values = array($uName, $email, $passHash);

            $res = $con->insert($fields, $values, 'users');

            if ($res) echo "1 Record Inserted";

<form action="register.php" method="POST" enctype="multipart/form-data">
    Username: <input type="text" name="userName" required>
    <br />
    Email: <input type="email" name="email" required>
    <br />
    Password: <input type="passWord" name="passWord" required>
    <br />
    <input type="submit" name="submit" value="Register">

Try the following changes:

$queryFields = implode(",", $fields);

$queryValues = implode('","', $data);

$insert = 'INSERT INTO '.$table.'('.$queryFields.') VALUES ("'.$queryValues.'")';
