## What it is
phptrace is a low-overhead tracing and troubleshooting tool for PHP, consisting of a PHP extension and a CLI binary. It traces function calls, request information, and runtime status of live PHP processes, useful for diagnosing blocking and heavy-load issues in production.

## Use cases
- trace function calls of a running PHP process
- debug blocking or slow PHP scripts in production
- inspect runtime status of php-fpm workers
- filter traces by function, class, or URL
- find performance bottlenecks in PHP applications

## When to choose
- you need to debug a live PHP process without restarting it
- you want low-overhead tracing safe for production environments
- you need to see which functions a PHP script is calling in real time

## When to avoid
- you need distributed tracing across services - use its successor Molten or OpenTracing-based tools
- you are not working with PHP
- you need a maintained tool with recent updates - the last release was in 2018
