1 # xhprof for PHP7 and PHP8
2 [![Build Status](https://travis-ci.com/longxinH/xhprof.svg?branch=master)](https://app.travis-ci.com/github/longxinH/xhprof) [![Build status](https://ci.appveyor.com/api/projects/status/dornfeel5yutaxte/branch/master?svg=true)](https://ci.appveyor.com/project/longxinH/xhprof/branch/master)
4 XHProf is a function-level hierarchical profiler for PHP and has a simple HTML based navigational interface. The raw data collection component is implemented in C (as a PHP extension). The reporting/UI layer is all in PHP. It is capable of reporting function-level inclusive and exclusive wall times, memory usage, CPU times and number of calls for each function. Additionally, it supports ability to compare two runs (hierarchical DIFF reports), or aggregate results from multiple runs.
6 This version supports PHP7 and PHP8

35 |xhprof.output_dir | "" | All |Output directory|
36 |xhprof.sampling_interval | 100000 | >= v2.* | Sampling interval to be used by the sampling profiler, in microseconds|
37 |xhprof.sampling_depth | INT_MAX | >= v2.* | Depth to trace call-chain by the sampling profiler|
38 |xhprof.collect_additional_info | 0 | >= v2.1 | Collect mysql_query, curl_exec internal info. The default is 0. Open value is 1|

49 - `XHPROF_FLAGS_NO_BUILTINS` do not profile builtins
50 - `XHPROF_FLAGS_CPU` gather CPU times for funcs
51 - `XHPROF_FLAGS_MEMORY` gather memory usage for funcs
66 - `wt` The execution time of the function method is time consuming
67 - `ct` The number of times the function was called
68 - `cpu` The CPU time consumed by the function method execution
69 - `mu` Memory used by function methods. The call is zend_memory_usage to get the memory usage
70 - `pmu` Peak memory used by the function method. The call is zend_memory_peak_usage to get the memory
