Logging

Logging

Yii provides a powerful logging framework that is highly customizable and extensible. Using this framework, you can easily log various types of messages, filter them, and gather them at different targets, such as files, databases, emails.

Using the Yii logging framework involves the following steps:

• Record log messages at various places in your code;
• Configure log targets in the application configuration to filter and export log messages;
• Examine the filtered logged messages exported by different targets (e.g. the Yii debugger).

In this section, we will mainly describe the first two steps.
