Hey all, got a slight problem, where for some reasons my variables

At least in PHP 5.2.1 on windows xp (for testing only), the class name
Parent is a reserved class name, you cannot define a class by that name.
{
$private type;
public function __construct()

}
public function GetType()
{
return $this->type;

class Child implements Parent
{
$public function __construct()
public should not be prefixed with '$'
you are missing your open '{' for this method
You need to call
parent::__construct();
$this->type= 'Child';
}
}
$Child= new Child();
echo $Child->getType;
also, you are calling a method, not accessing a property.
it should be
echo $Child->getType();
Can u see any reason why the type would return null?
Thanks,
Jeff
well, for starters, I think it is incorrect to have public and private
prefixed with a '$'. But then you have it on some, but not all of
them.....
Besides that, does it give you an error? What does it return if it
doesn't return 'Child'??
What version of PHP are you running on. there is a differnet way the
constuct() method gets called.
public and private are not available in versions older than php 5
in PHP version < 5 you have to have a method named the same as the class
that you are creating.
Try this:
<?php
class myParent {
# private $type; #<--- With this, I cannot echo $type
var $type; #<--- With this, I CAN echo $type
public function __construct() {
}
public function myParent() {
$this->__construct();
}
public function getType() {
echo $this->type;
}
}
class myChild extends myParent {
public function __construct() {
parent::__construct();
$this->type = 'Child';
}
public function myChild() {
$this->__construct();
}
}
$Child = new myChild();
echo $Child->getType();
?>
ok, responded too quickly. Roman has it right with the settype method
This now works.
<?php
class myParent {
private $type;
public function __construct() {
return $this;
}
public function myParent() {
return $this->__construct();
}
public function setType($value='') {
$this->type = $value;
}
public function getType() {
return $this->type;
}
}
class myChild extends myParent {
public function __construct() {
parent::__construct();
$this->setType('Child');
return $this;
}
public function myChild() {
return $this->__construct();
}
}
$Child = new myChild();
echo $Child->getType();
?>
