# Introduction
This analyzer ensures that your application does not have the Xdebug extension loaded in a non-local environment (e.g. production or staging).
If you have Xdebug loaded in a production environment:
- It will significantly impact your performance. The Xdebug engine attaches to your PHP process and receives messages to stop at breakpoints.
- It can cause security issues as Xdebug tends to open ports on the server, which may be exposed to potential attackers depending on your firewall configuration.
# How To Fix
Simply uninstall Xdebug on your production or staging servers. You may refer the Xdebug documentation (opens new window) on how to do so.
# Skip Condition
This analyzer is skipped for local or testing environments.
