README

The package contains implementation of aeatech/snapshot-profiler-contracts to profile applications with xhprof. It can be used for production profiling.

System requirements:

• PHP >= 8.2
• ext-xhprof
• xhgui (tested on xhgui/xhgui:0.22.1)

Installation (Composer):

composer require aeatech/snapshot-profiler-xhprof

Quick start
