phpspy 进行php 项目性能分析

phpspy 是基于c 编写的利用了ptrace 的php 性能分析工具,支持apache ,fpm sapi 注意php 主要支持7.0+


为了方便,构建了docker 镜像,大家可以直接使用

                                       above PIPE_BUF (4096) may lead to
                                       interlaced writes across threads.

                                       at `varspec`, which has the format:
                                       e.g., xyz@/path/to.php:10-20
  -g, --peek-global=<glospec>        Peek at the contents of a global var
                                       located at `glospec`, which has

                                       where <global> is one of:
                                       e.g., server.REQUEST_TIME
  -t, --top                          Show dynamic top-like output
  • 参考运行命令
docker run -it --cap-add SYS_PTRACE dalongrong/phpspy ./phpspy/phpspy -V73 -r -- php -r 'sleep(1);'





类似的工具xdebug 以及php-profiler也是不错的选择,docker 镜像dalongrong/phpspy 直接可以使用,后续会写直接集成到容器中的玩法
