Is it possible to use an object that was created during a class' construction within the member methods of that class?
Ex
<?php
include ('AClass.php');
class Auto_Cart {
function Auto_Cart() {
$aclass = new AClass();
}
function DoSomething() {
$aclass->amemberfunction();
}
}
?>
When I call DoSomething, it should call aclass->amemberfunction()
I think my syntax is wrong but maybe this just isn't possible. Can you help me out?
Thanks!
You need to store the instance of AClass as a member variable (aka "property") of the instance of Auto_Cart.
Assuming PHP4 by the style of your constructor
class Auto_Cart
{
/** @var $aclass AClass */
var $aclass;
function Auto_Cart()
{
$this->aclass = new AClass();
}
function DoSomething()
{
$this->aclass->amemberfunction();
}
}
An just as an FYI, in OOP-speak we call this composition - meaning one object creates and stores a reference to another object automatically or "lazily".
You need to store a reference to the object in order to use it later, as it will be lost when the constructor function exits. Try storing it as a member of your Auto_Cart object, like this:
<?php
include ('AClass.php');
class Auto_Cart {
function Auto_Cart() {
$this->aclass = new AClass();
}
function DoSomething() {
$this->aclass->amemberfunction();
}
}
?>
