php運行狀態報表工具：php-timer

最近寫了一個非同步mysql用戶端的封裝，想與傳統的串列方式做下效能對比。包括已耗用時間、記憶體使用量情況等資訊。在github和packagist上搜尋並沒有找到自己想要的，xhprof又太大了，結果也太複雜，不符合現在的需要。所以決定自己寫一個package，來實現對php指令碼已耗用時間和記憶體使用量情況的監控，並產生報告。

範例程式碼：

requiredirname(dirname(__FILE__)) . DIRECTORY_SEPARATOR .'vendor'. DIRECTORY_SEPARATOR .'autoload.php';//初始化，設定記憶體單位$timer=new\Jenner\Timer(\Jenner\Timer::UNIT_KB);//記錄a狀態$timer->mark('a');sleep(2);//記錄b狀態$timer->mark('b');sleep(3);//記錄c狀態$timer->mark('c');sleep(4);//記錄d狀態$timer->mark('d');//列印總體報告（不包含差值）$timer->printReport();//擷取總體報告，返回數組$report=$timer->getReport();//擷取一個mark的報告$a_report=$timer->getReport('a');print_r($a_report);//列印a狀態和b狀態的差異資訊，包含已耗用時間、使用記憶體等$timer->printDiffReportByStartAndEnd('a','b');//擷取a狀態和b狀態的差異報告$ab_diff_report=$timer->getDiffReportByStartAndEnd('a','b');//列印第一個mark和最後一個mark之間的差異資訊$timer->printDiffReport();//擷取第一個mark和最後一個mark之間的差異資訊$diff_report=$timer->getDiffReport();

輸出結果：
