Codeigniter password_verify method
<p>I have this   method in my Codeigniter (version 3.0) login module. It works fine but is this safe? Is any better solution to check login and password using PHP password_verify?
(PHP 5.6,
MySQL 5.0).</p>

<pre><code>        $user = $this-&gt;input-&gt;post('username');
        $password = $this-&gt;input-&gt;post('password');
        $myquery = $this-&gt;db-&gt;query("SELECT * FROM users WHERE user = '$user'");
        $row = $myquery-&gt;row();

        if (isset($row))
        {
            //Using hashed password - PASSWORD_BCRYPT method - from database
            $hash = $row-&gt;password;


            if (password_verify($password, $hash)) {

                echo 'Password is valid!';


            } else {

                echo 'Invalid password.';

            }


        } else{

            echo 'Wrong user!';
        }
</code></pre>
