构造函数中的摘引

<?php <br />
class Foo{<br />
	function Foo($name){<br />
		global $globalref;<br />
		$globalref[] = &$this;<br />
		<br />
		$this->setName($name);<br />
		<br />
		$this->echoName();<br />
		<br />
	}<br />
	<br />
	function echoName()<br />
	{<br />
		echo '<br />',$this->name;<br />
	}<br />
	<br />
	function setName($name)<br />
	{<br />
		$this->name = $name;<br />
	}<br />
}<br />
?><br />
<br />
<br />
<?php <br />
$bar1 = new Foo('set the name is php');<br />
<br />
$bar1->echoName();<br />
$globalref[0]->echoName();<br />
<br />
//print_r($globalref);<br />
//手册上说 如果重新设置个新name $bar1 和 $globalref[0] 是不一样的 但是测试的时候 这里输出是一样 <br />
$bar1->setName('set the name is java');<br />
$bar1->echoName();<br />
$globalref[0]->echoName();<br />
