我有类DatabaseAccess,我继承了两个类:TeamAccess和StatisticsAccess。现在,当我从StatisticsAccess创建TeamAccess实例时,它的类型是StatisticsAccess吗?这里发生了什么?
继承代码
class StatisticsAccess extends DatabaseAccess {
public function getMatchesById($matchesid) {
$teamAccess = new TeamAccess();
print_r(new TeamAccess);
}
}
class TeamAccess extends DatabaseAccess {
function __construct() {
parent::__construct();
}
}
print_r显示StatisticsAccess对象。

在StatisticAccess中创建TeamAccess类只会创建一个TeamAccess类,就像在类之外创建它一样。
class StatisticsAccess extends DatabaseAccess {
public function test() {
$teamAccess = new TeamAccess();
//print_r(new TeamAccess);
echo "teamAccess var class: " . get_class($teamAccess);
echo "<br/>this class: " . get_class($this);
}
}
$sa = new StatisticsAccess;
$sa->test()
?>
返回:
//teamAccess var class: TeamAccess
//this class: StatisticsAccess
