2019独角兽企业重金招聘Python工程师标准>>> 
一种是函数，一种是类方法
<!-- lang: php -->
$func = new ReflectionFunction('showmessage');
var_dump($func->getFileName());
$func = new ReflectionMethod('classname','function');
var_dump($func->getFileName());
-
查询哪个函数调用了当前函数 在当前函数里面
<!-- lang: php -->
print_r(debug_backtrace()); 结果：`Array ( [0] => Array ( [file] => /data/apache/www/xxx/kanfangtuan.xxx.cn/lib/yii-1.1.14.f0fee9/framework/base/CComponent.php [line] => 152 [function] => setModules [class] => CModule [object] => CWebApplication Object ( [defaultController] => index [layout] => main [controllerMap] => Array ( )
