If your PHP framework is not listed here, the agent detects your entry points as PHP Web and names the business transactions based on the first two segments of the URI — the default naming convention for PHP Web transactions. So it is still possible to monitor applications on unsupported frameworks. Laravel BTs are detected as symfony, as laravel itself is built on top of symfony.


There are few limitations of the PHP Agent. The PHP Agent does not:

  • Support Zend Monitor
  • Officially support plug-ins that encrypt and, or obfuscate PHP code such as Zend Guard or ionCUBE Loader
  • Support compatibility with the Xdebug module
  • Support the pcntl_fork function which forks the child/sub-processes
