傳值，傳址

經過大半年在javascript中游蕩

這次，再次看回php

沒用& 是引用，引的是堆中的那個  

有用&也是引用，引的是棧中的那個

<?php
function dome(){
	return 'wawa';
}
function ui($className){
	$info = 'my name';
	$b = new $className();
	$x = dome();
	$d = new Config();
	$h = $GLOBALS;
	
}

class Config {
	public function __construct() {
		$this->path = 'src/';
		$this->description = 'mycofig';
	}
	public function setPath(){
		
	}
	public $compile;
	private $theme;
	
	
}

$domElement = 'v';


////main start
$a = new Config();
$a->compile = 'just for me';
$v = $a;
$v->compile = 'mmm';
$g = &$a;
$a = 'vvvv';
////main end

ui('Config');

$onCreate = 'list';

簡單的就是下面那樣

$w = 'wwww';
$g = $w;
$ww = &$w;
$ww = 'bbbb';
