PHP Method chaining Confusion

Question

i have been lately introduced to method chaining, and am not sure if what I\'m doing here is illegal, or I\'m doing it wrong. I have a database Class like:

    c         


        

Answer 1

If you want to using method chaining, what you should do is return $this.

public function query($query)
{
    $this->last_query = $query;
    $this->resultset = mysql_query($query, $this->connection);
    return $this;
}

Then you can do this:

$db->query("SELECT * FROM users WHERE name='JimmyP'")->fetchObject();
