🎨将xhprof产生的数据转为可以生成flame graph火焰图的格式并生成火焰图

安装

composer require sy-records/xhprof2flamegraph

使用

vendor/bin目录下有两个可执行文件，执行命令

./vendor/bin/xhprof2flamegraph -f ./test.xhprof | ./vendor/bin/flamegraph.pl > out.svg

替换对应的路径信息

-f 为指定的xhprof日志文件，json格式 （如果日志文件为serialize序列化后的数据，请修改src/Command/Command.php文件中的第40行），自动处理json和serialize格式的数据
