你可以在对象本身之外使用get_class_vars
函数:
$a = new a();
$class_vars = get_class_vars(get_class($a));
foreach ($class_vars as $name => $value) {
if ($value > 0) {
echo "$name : $value\n";
}
}

将此方法放入您的类中,它将返回数组中的所有变量:
public function test() {
$vars = get_object_vars($this);
$r = array();
foreach($vars as $k => $v) {
if($v > 0){ $r[$k] = $v; }
}
return $r;
}
