java - troubles with variables in PHP -

i new in php java background. in confusion next code:

class pupil { //public $name; public function __construct($name) { $this->name=$name; } public function showname() { echo $this->name; } }

on above code if comment line public $name; still works. however, in java not supposed work. want understand behavior in php.

php uses implicit declaration of properties. can declare , assign property anywhere (even outside class).

<?php $object1 = new user(); $object1->name = "alice"; echo $object1->name; class user {} ?>

would work fine , print "alice"...

java php
