stdClass Object ( [out] => 输出问题

[sunbingyan503126]

<?php
	$ip =  gethostbyname($SERVER_ADDR);
	$wsdl = "http://$ip:8080/xjxl/services/QueryService?wsdl";
	$client = new SoapClient($wsdl);
	$student = $client -> getQueryStudentList(
	array(
	'in0'=>$studentName,'in1'=>$gender,'in2'=>$enterDate,
	'in3'=>$birthday,'in4'=>$collegeName,'in5'=>$majorName,
	'in6'=>$trainLevel
	));
	print_r($student);
?>

输出结果是
stdClass Object ( [out] => 孙冰岩,男,2009-07-17 00:00:00.0,2009-07-17 00:00:00.0,装甲兵工程学院,计算机科学,本科 )
我如何才能得到下面的结果

姓名：孙冰岩
性别：男
学历：本科

就是要提取出我想要的元素，分别打印出来

[sunbingyan503126]

输出结果是

stdClass Object ( [out] => stdClass Object ( [string] => com.xsoft.pojo.edu.student.StudentHistory@136a0bc ) )

这样我该怎么得到其中的数据

[foolbirdflyfirst]

$r = explode(',',$student->out);
echo "姓名:{$r[0]}<br/>";
echo "性别:{$r[1]}<br/>";
echo "学历:{$r[6]}";
