get value from array inside object

Question

if i do

var_dump( $poll->vote_form() );

class method returns an array which is what i want

array (size=3)
  'id' => int 41
  'name' => string 'sg' (length=2)
  'options' => 
    array (size=4)
      116 => string 'dsg' (length=3)
      117 => string 'dsg' (length=3)
      118 => string 'dg' (length=2)
      119 => string 'gd' (length=2)

but when i do

echo $poll->vote_form['name'];

i get error

Undefined property: poll::$vote_form

hm what seems to be the problem? this is the method of class poll

public function vote_form()
{
            ...
    $form = array('id' => $poll_id, 'name' => $poll_name, 'options' => $poll_options);
    return $form;
}

You jsut called the method of the poll calss and stores whatever it returned in a variable. SO now $data is an array and you can access it as a normal array now

Because in your code example you try to access a class property called $vote_form instead of a method vote_form(). With PHP > 5.4 you can also write $poll->vote_form()['name']; but my personal oppinion is that you should work with Marko's solution for compatibility with older PHP versions.

well funny thing, i had that code yesterday and it worked perfectly but on different computer (it could be because php version is higher?). On this computer it throws error - Parse error: syntax error, unexpected '[',....
