By default, Datadog supports all PHP web frameworks out of the box, with either framework-level instrumentation, or generic web tracing.
Framework-level instrumentation includes tracing of internal methods and framework specific tagging.
Generic web tracing includes a web.request span to track latency and errors that originated from the call, in addition to spans for supported libraries — for example: database and HTTP clients.
The following table enumerates some of the frameworks and versions Datadog successfully traces.

| Module | Versions | Support Type | Instrumentation level |

Datadog is continuously adding more support for in-depth tracing for PHP web-frameworks. To request support for additional span metadata and framework internals, contact our awesome support team.
Tracing from the CLI SAPI is disabled by default. To enable tracing of PHP CLI scripts, set DD_TRACE_CLI_ENABLED=true.

The call stack is limited on PHP 5. See the deep call stack troubleshooting page for more details.
Instrumenting generators is not supported on PHP 5 and PHP 7.
We do not offer support for tracing processes forked using pcntl. When a call to pcntl_fork is detected, we disable tracing in the forked process. The main process is still be traced.
If the application invokes pcntl_unshare(CLONE_NEWUSER); and the tracer is installed, the application will fatally crash. This happens because unshare with CLONE_NEWUSER requires the process not to be threaded, while the PHP tracer uses a separate thread to send traces to the Datadog Agent without blocking the main process.
