When this extension is used, a debugger toolbar will appear at the bottom of every page. The extension also provides a set of standalone pages to display more detailed debug information. Requirements ------------ [](#requirements) - PHP 8.1 or higher. Installation ------------ [](#installation) The package could be installed with [Composer](https://getcomposer.org): ``` composer require yiisoft/yii-debug --dev ``` > The debug extension also can be installed without the `--dev` flag if you want to collect data in production. Specify the necessary collectors only to reduce functions overriding and improve performance. General usage ------------- [](#general-usage) Once the extension is installed, modify your `config/common/params.php` as follows: ``` return [ 'yiisoft/yii-debug' => [ 'enabled' => true, ], // ... ]; ``` All included collectors start listen and collect payloads from each HTTP request or console run. Install both [`yiisoft/yii-debug-api`](https://github.com/yiisoft/yii-debug-api) and [`yiisoft/yii-dev-panel`](https://github.com/yiisoft/yii-dev-panel)to be able to interact with collected data through UI. Documentation ------------- [](#documentation) - [Guide](docs/guide/en/README.md) - [Internals](docs/internals.md) If you need help or have a question, the [Yii Forum](https://forum.yiiframework.com/c/yii-3-0/63) is a good place for that. You may also check out other [Yii Community Resources](https://www.yiiframework.com/community). License ------- [](#license) The Yii Debug Extension is free software.
