Why is the Debugger outputting the object as a serialized string?

Question

Yii

When I do this Yii::info($someobject),
I get something like this in the debugger log:

unserialize('O:36:"backend\\models\\PriceFileColumnsOrder":9:{s:44:"' . "\0" . 'backend\\models\\PriceFileColumnsOrder' . "\0" . '_items";a:0:{}s:36:"' . "\0" . 'yii\\db\\BaseActiveRecord' . "\0" .

How to achieve pretty output as var_dump without Yii::info( print_r($someobject, true) )?

Answer 1

Serialize the object in advance in the desired beautiful format.
The logger in Yii is terrible: there is a violation of all possible OOP principles due to embedding the logger in BaseYii, and non-compliance with PSR-3, and bicycle building, and the lack of the ability to pass the context.
Yii developer Tian said he thinks his framework's users are too dumb to use a PSR-3 compliant logger: https://github.com/yiisoft/yii2/issues/1660
