# PHPStorm

PHP

As of 2020.1, PHPStorm provides stubs for `\BlackfireProbe` internal class, which is [provided by the Blackfire extension](../../php/integrations/sdk#php-blackfireprobe-internal-class). These stubs give you **code completion on all available methods of BlackfireProbe class**.

## Configuration

Blackfire stubs are not enabled by default in PHPStorm. To activate them, you need to:

1. Go to PHPStorm settings;
2. Go to *Language and Frameworks*, then *PHP*;
3. Click on *PHP Runtime* tab;
4. Unfold *Others*, and check **blackfire** in the list;
5. Validate your change by clicking *OK*.
