Question

I have this code:

$db->get()->query()

Now i want the get method’s return to depend on:

$db->get()
return $db->query var;

but

$db->get()->query()

the get() method will return $this

Updated:
You can’t change the return depending on whether you’ve chained the code (which is what it looks like you want to do) – however for this particular problem you can implement the too string method which will ‘appear’ to do the same thing 🙂

<?php
class DB {

  private $query = 'some query';

  public function get()
  {
    return $this;
  }

  public function query()
  {
    // do the query function
  }

  public function __toString()
  {
     return $this->query;
  }
}

$db = new DB;
echo $db->get(); //prints 'some query'
$db->get()->query(); // runs the query() method
