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+

参考使用

为了方便，构建了docker 镜像，大家可以直接使用

• 支持的命令

docker run -it  dalongrong/phpspy   ./phpspy/phpspy --help

                                       at `varspec`, which has the format:

                                       <varname>@<path>:<start>-<end>

                                       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);'

效果

说明

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
