Reli 是一个用PHP编写的采样分析器（或VM状态检查器）。它可以从进程外部读取有关运行PHP脚本的信息。它是一个独立的CLI工具，因此目标程序不需要任何修改。

sudo /usr/local/php-8.2.14/bin/php ./reli i:eg -p 21845530x55e17fe1b1a04、跟踪当前进程正在执行的操作码
如果用户想分析一个真正的CPU受限的应用程序，那么他或她不仅想知道哪一行是慢的，还想知道操作码是什么。在这种情况下，使用 --template=phpspy_with_opcode 与 inspector:trace 或 inspector:daemon 。
sudo /usr/local/php-8.2.14/bin/php ./reli i:trace --template=phpspy_with_opcode -p 2184553输出如下所示
0 EventBase::loop <internal>:-11 Workerman/Events/Event::loop /home/www/build/webman01/vendor/workerman/workerman/Events/Event.php:193:ZEND_DO_FCALL2 Workerman/Worker::run /home/www/build/webman01/vendor/workerman/workerman/Worker.php:2435:ZEND_DO_FCALL3 Workerman/Worker::forkOneWorkerForLinux /home/www/build/webman01/vendor/workerman/workerman/Worker.php:1555:ZEND_DO_FCALL4 Workerman/Worker::forkWorkersForLinux /home/www/build/webman01/vendor/workerman/workerman/Worker.php:1397:ZEND_DO_FCALL5 Workerman/Worker::forkWorkers /home/www/build/webman01/vendor/workerman/workerman/Worker.php:1371:ZEND_DO_FCALL6 Workerman/Worker::runAll /home/www/build/webman01/vendor/workerman/workerman/Worker.php:549:ZEND_DO_FCALL7 <main> /home/www/build/webman01/start.php:112:ZEND_DO_FCALL...当前执行的操作码成为调用堆栈的第一帧。因此，像火焰图这样的可视化跟踪可以显示操作码的使用情况。
出于信息目的，执行操作码也被添加到调用帧的每一端。除了第一个帧，函数调用的操作码（如ZEND_DO_FCALL）应该出现在那里。如果在目标流程中启用了JIT，则此信息可能会稍微不准确。
火焰图是由 Brendan Gregg 发明的一种可视化方法，用于展示某一种系统资源或性能指标，是如何定量分布在目标软件里所有的代码路径上的。
