The Symfony profiler bundle is a powerful tool that provides a detailed insight into the performance and behavior of your Symfony application. Here's how you can use it to debug your application:
- Enable the profiler bundle: Ensure that the profiler bundle is enabled in your Symfony application. This can be done by adding the following line to your config/bundles.php file:
1
|
SymfonyBundleDebugBundleDebugBundle::class => ['dev' => true, 'test' => true],
|
- Enable the profiler toolbar: The Symfony profiler toolbar displays a summary of the profiler data for the current request. To enable it, add the following line to your base template file:
1
|
{{ render(controller('web_profiler.controller.profiler::toolbarAction')) }}
|
- Analyze the profiler data: After enabling the profiler, you can analyze the profiler data for each request by clicking on the profiler toolbar. This will display a detailed breakdown of the request, including timing information, database queries, and other useful information.
- Use the debug panel: The Symfony profiler also provides a debug panel that displays a detailed breakdown of the request. This can be accessed by clicking on the "Debug" tab on the profiler toolbar.
- Use the web debug toolbar: The web debug toolbar provides a set of debugging tools that can help you diagnose and fix issues with your Symfony application. This can be enabled by adding the following line to your config/packages/dev/web_profiler.yaml file:

|
web_profiler:
toolbar: true
|
- Use the profiler in production: Although the Symfony profiler is primarily used for development and testing purposes, it can also be used in production environments to diagnose and fix performance issues. To enable the profiler in production, you need to add the following lines to your config/packages/prod/web_profiler.yaml file:
1
2
|
web_profiler:
intercept_redirects: true
|
By following these steps, you can use the Symfony profiler bundle to debug your application and gain valuable insights into its performance and behavior.
