Consider the following code:
<?php
class Apple {
public $cat;
public function __construct() {
$orange = new Orange();
}
}
$apple = new Apple();
class Orange {
public function dog() {
echo $apple->cat;
}
}
?>
The echo insider of dog() doesn't work as Orange doesn't have access to
properties and methods of the Apple object. The only way I am aware of to make
it work is to pass the first object in by reference, like this:
<?php
class Apple {
public $cat;
public function __construct() {
$orange = new Orange($this);
}
}
$apple = new Apple();
class Orange {
public $apple;
public function __construct(&$apple) {
$this->apple = $apple;
}
public function dog() {
echo $this->apple->cat;
}
}
?>
Is there any better or simpler (syntactically) way?
I could pass it into dog() every time I call it like this:
<?php
class Apple {
public $cat;
public function __construct() {
$orange = new Orange();
}
}
$apple = new Apple();
class Orange {
public function dog(&$apple) {
echo $apple->cat;
}
}
$apple->orange->dog($apple);
?>
That gets me the simplicity I want insider of dog(), but adds complexity ouside
of dog each time I have to call it and complicates things with other variables
I have to pass in. Any way to pass it in automatically? I'm thinking of __set
and overloading concepts but haven't been able to come up with a solution.
