<?php class base_class { function say_a() { echo "'a' - said the " . __CLASS__ . "<br/>"; } function say_b() { echo "'b' - said the " . get_class($this) . "<br/>"; } } class derived_class extends base_class { function say_a() { parent::say_a(); echo "'a' - said the " . __CLASS__ . "<br/>"; } function say_b() { parent::say_b(); echo "'b' - said the " . get_class($this) . "<br/>"; } } $obj_b = new derived_class(); $obj_b->say_a(); echo "<br/>"; $obj_b->say_b(); ?>
执行结果：
'a' - said the base_class 'a' - said the derived_class 'b' - said the derived_class 'b' - said the derived_class
tips:
1.__CLASS__获取的是原汁原味的类名
2.parent()继承父类的代码
