php function get_class() in superclass

php function get_class()在类继承使用时需要特别注意。

<?php
abstract class bar {
    public function __construct() {
        var_dump(get_class($this));
        var_dump(get_class());
    }
}

class foo extends bar {
}

new foo;
?>

The above example will output:

string(3) "foo"
string(3) "bar"
