I sometimes come across pieces of code that look like $obj->something->variable... how is that possible? I would want to understand how that is done...

I guess yes since it is an OOP language.

for example:

class->arrayofclasses[1]->variable

i guess you can called it obj within obj; subclass..

just like a regualr class that embeded another class.

Code: [ Select ]
<?php

class MyFirstClass {

public $aVariableFromFirst = "hello";
}

class MySecondClass {

public $aVariableFromSecond = new MyFirstClass();
}

?>
  1. <?php
  3. class MyFirstClass {
  5. public $aVariableFromFirst = "hello";
  6. }
  8. class MySecondClass {
  10. public $aVariableFromSecond = new MyFirstClass();
  11. }
  13. ?>


Code: [ Select ]
<?php

$obj = new MySecondClass();
echo $obj->aVariableFromSecond->aVariableFromFirst;

?>
  1. <?php
  3. $obj = new MySecondClass();
  4. echo $obj->aVariableFromSecond->aVariableFromFirst;
  6. ?>

Ahh... this should fix a huge problem that I have with some of my classes. Thanks so much Spork and IcyDragoon.
