简单PHP性能记录工具

最近写了一个异步mysql客户端的封装,想与传统的串行方式做下性能对比。包括运行时间、内存使用情况等信息。在github和packagist上搜索并没有找到自己想要的,xhprof又太大了,结果也太复杂,不符合现在的需要。所以决定自己写一个package,来实现对php脚本运行时间和内存使用情况的监控,并生成报告。

项目地址:https://github.com/huyanping/php-timer  

示例代码:  

require dirname(dirname(__FILE__)) . DIRECTORY_SEPARATOR . 'vendor' . DIRECTORY_SEPARATOR . 'autoload.php';

//初始化,设置内存单位
$timer = new \Jenner\Timer(\Jenner\Timer::UNIT_KB);
//记录a状态
$timer->mark('a');
sleep(2);
//记录b状态
$timer->mark('b');
sleep(3);
//记录c状态
$timer->mark('c');
sleep(4);
//记录d状态
$timer->mark('d');
//打印总体报告(不包含差值)
$timer->printReport();
//获取总体报告,返回数组
$report = $timer->getReport();
//获取一个mark的报告
$a_report = $timer->getReport('a');
print_r($a_report);
//打印a状态和b状态的差异信息,包含运行时间、使用内存等
$timer->printDiffReportByStartAndEnd('a', 'b');
//获取a状态和b状态的差异报告
$ab_diff_report = $timer->getDiffReportByStartAndEnd('a', 'b');
//打印第一个mark和最后一个mark之间的差异信息
$timer->printDiffReport();
//获取第一个mark和最后一个mark之间的差异信息
$diff_report = $timer->getDiffReport();

输出结果:
