Question

php如何把全局变量传到类里面？

我认为应该写到「在类前面声明」，或者写到「构造函数」，这样子就可以不需要重复用global关键字。
请高手教一教怎么写。

<?php
$my_car = "Koenigsegg";
$my_house = "Village between City";
class Dream {
function getDream() {
global $my_car;
global $my_house;
echo '<p>I want to have <b>' . $my_car . '</b>, even though I am living in <em>' . $my_house . '</em>.</p>';
}

function outDream() {
global $my_car;
global $my_house;
echo '<p>I can not have <b>' . $my_car . '</b>, because I living in <em>' . $my_house . '</em>.</p>';
}
}

$dreams = new Dream;
$dreams->getDream();
$dreams->outDream();
?>
