Problem with objects

JelloPowder

<?                                           

 class Tmp {                                 

  var $rcptlist;                             

  function Tmp() {                           

    $rcptlist = new RcptList();              

  }                                         

}                                           

 class RcptList {                             

  var $recipients;                           

  function RcptList() {                     

    $recipients = array('foo','bar','foobar');
  }             

}               

  $test = new Tmp();
  var_dump($test);
 ?>

Gives : object(tmp)(1) { ["rcptlist"]=> NULL }

Why is rcptlist NULL? Shouldn't it still be initiated from the constructor? The same problem occurs if I var_dump $rcptlist after its constructor has run: the $recipients array is empty.

Thanks

Yes Vbabiy, but you have a dollar sign after '->' which is incorrect.

JelloPowder, this is the correct syntax:

$this->rcptlist = new RcptList();

$this->recipients = array('foo','bar','foobar');

🙂

I thought i was close oops My Bad

I've updated it for the following:

<?


class Tmp {
  var $rcptlist;

  function Tmp() {
    this->rcptlist = new RcptList();
    var_dump(this->rcptlist);
    echo '<br />';
  }
}

class RcptList {
  var $recipients;

  function RcptList() {
    this->recipients = array('foo','bar','foobar');
  }
}

$test = new Tmp();
var_dump($test);

?>

And now it gives the following error: Parse error: parse error, unexpected T_OBJECT_OPERATOR in /home/oregon/public_html/phptests/tests.php on line 8. Hrm....almost as though it didn't know it was an object.

Ah! slaps his forehead

this requires a $ before it, thanks for the help 🙂

Get into the habit of using full opening php tags as if you want to port your code and somebody has tweaked the ini file to not allow short tags then you'll want to cry.

And ifyou're using php 4 creating objects with $obj = &new SomeObject is good practise, you can find out why in the documentation.

Mark this as resolved with the Thread Tools if it's done.
