[SOLVED] Calling Functions

[aim25]

Is it possible to call a function within another function?

 

Example:

<?php

class MAIN {

function A() {
.. some code
}

}

class SOMETHING extends MAIN {

function B() {
$var = new MAIN;
$var->A();
}

}

?>

Uhh.....yes?  Have you ever done:

 

function truncate($string, $length=50) {

  return substr($string, 0, $length);

}

 

Or something like that?  O_O  Really strange question. =/

That doesn't really answer the question... Sorry.

[DarkWater]

That completely answers the question.  I said yes.  I've just never heard anyone ask that question...Why wouldn't you be able to call a function in another function?

My bad, the i focused on teh code you provided.

Yes you can do that, however when you do $var = new MAIN you're creating a new instance of the main class.

 

If all you want to do is call function A from the function B in SOMETHING class then do parent::A() instead;

Yes, if you just want to call the function with the current instance of B that you are using, you'll use the parent:: scope.  If you actually want a new instance, then you can do it your way.  What are you trying to accomplish?
