[RESOLVED] class property inheritance

[private_click]

hello.

i have some problem with object property inheritance.
take this code for example:

<?php
class base {
	public $v;

public function setV($value)
{
	$this->v = $value;
}

public function getV() {
	return $this->v;		
}
}

class child extends base {

}

$base = new base();
$base->setV("val");
print $base->getV(); // this works fine, it prints "val"

$child = new child();
print $child->getV(); // this doesn't
?>

why is $child->getV() not returning anything?
also, how can i fix this?

Thanks.

Because you did not use setV. For example, try this:

<?php
class base {
    public $v;

public function setV($value) {
    $this->v = $value;
}

public function getV() {
    return $this->v;
}
}

class child extends base {

}

$base = new base();
print $base->getV();

Why doesn't the last line print anything?

Call $child->setV("whatever").

thx for your response.

i had the wrong idea that if i set 'v' in an instance of 'base', any object that has inheritance with base class will hold value of 'v' set in base instance 🙂

i solved the problem by using always the same instance (singleton pattern)
