profiler-docker

Dockerized command-line PHP 7 profiler (XHPROF-compatible)

Portable docker image with PHP 7.4 and tideways extension installed.

Profiling is started automatically with auto_prepend_file configuration.

Usage

docker run --rm -v $(pwd):/code phperf/php-profiler php test_me.php

You can also generate SVG call graph adding SVG=1 ENV var (may take long time for big profiles)

docker run --rm -e SVG=1 -v $(pwd):/code phperf/php-profiler php test_me.php

After your script is finished xhprof report and SVG graph will be saved:

Performance index: 0.00037335238456726
Nodes in report: 33
Saving report to xhprof_report.1518411787.448.serialized

You can analyze profiling report with xh-tool

xh-tool top xhprof_report.1518411787.448.serialized --limit 5 --strip-nesting

If you want to save profile data to a particular file, you can provide it with REPORT=<name>, you can use JSON format if name ends with .json

docker run --rm -e REPORT=rep.json -v $(pwd):/code phperf/php-profiler php t2.php
