object oriented php help

i'm new to object oriented php

now I have a class

and wihtin the class I want to call a function with the $id
How do I call a function (that returns an array) and put it to an array.

I tried
$this->product= getM($this-->id);
but it's not working?
any suggestions as well for some good tutorial on this would be helpful.




function getM($id)

Can't you just do

$this->variable = array(1, 2, 3, 4, 5);

well the function opens the db and pullls a recordset to the array it returns

i'm having trouble calling the functions with the id

You will have to post more code for us to help.

a function external to the class ..

<?
$this->product=getM($this->id);
?>
or a function within the class (a class method) ??
<?
$this->product=$this->getM($this->id);
?>
