php var_dump($ object)或print_r($ object)到日志文件 [英] php var_dump($object) or print_r($object) to a log file

问题描述

这个问题是通用的，我只是想知道如何将对象转储到日志文件中.为了澄清问题，我通过一个例子进行详细说明.

This question is generic, and I would simply like to know how to dump objects to log files. In order to clarify things, i am elaborating through an example.

当某些事件发生时，我已经成功地使用了magento观察器来调用方法. 例如，我正在观察何时通过以下方式保存货件:

I have been successfully using magento observers to call methods when certain events happen. As an example, I am observing for when a shipment is saved via :

<sales_order_shipment_save_after>

并且我成功地调用了一个方法.我想抓住货物并将其简单地转储到日志文件中.例如.

and i'm successfully calling a method. I would like to grab the shipment and simply dump the object to a log file. eg.

public function newShipment(Varien_Event_Observer $observer)
{
    $shipment = $observer->getEvent()->getShipment();
    $shipId = $shipment->getId();
    Mage::log("shipment ({$shipId}) created/saved", null, 'shipments.log');
    //trying to dump $shipment data into the log file
    Mage::log("({var_dump($shipment)}) ------", null, 'shipments.log');
    Mage::log("----------------------------", null, 'shipments.log');
}

货件ID可以很好地打印到日志文件中，但是显然，它不会以我想要的方式转储对象，因为我编写的代码是错误的.

The shipment id is printed into the log file just fine, but obviously it does not dump the object the way i want it to as the code I have written is wrong.

任何人都可以告诉我如何将对象转储到日志文件中，也许可以给我一些有关一般日志记录的建议?

Can anyone tell me how I could dump an object to a log file and perhaps give me some advice on logging in general?

非常感谢.

推荐答案

如果您处于开发人员模式，则可以尝试该对象是否支持通过$object->debug()进行调试的输出.

If you are in Developer Mode you can try if the object supports debug output via $object->debug().
