## What it is
XHProf is a lightweight function-level hierarchical profiler for PHP, implemented as a C PHP extension with a PHP-based HTML reporting UI. It reports inclusive/exclusive wall time, CPU time, memory usage, and call counts per function, with diff and aggregate reports and callgraph visualization.

## Use cases
- profile php application performance
- find slow functions in php code
- compare two php profiling runs
- generate callgraph of php execution
- measure memory usage per php function
- profile php 8.4 application

## When to choose
- you need a lightweight, low-overhead function-level profiler for PHP
- you want browser-based reports with diff and callgraph views
- you need profiling support for modern PHP versions including 8.x

## When to avoid
- you need distributed tracing or continuous production profiling rather than on-demand function profiling
- you want a modern UI or integration with APM platforms like Datadog or New Relic
- you need profiling for languages other than PHP

## Facets
- artifact type: library
- maturity: maintenance
- function: benchmarking, monitoring, developer-tools
- domain: developer-tools, performance, web-development
- platform: php, windows, cross-platform
- tags: profiler, php-extension, pecl, callgraph, performance-analysis, hierarchical-profiling, linux, macos
