PHP简单性能检测类工具

一、概述
 该类主要是检测一段代码的运行时间,检测一些PHP效率问题。

二、使用方法
首先require该类
主要使用接口为begin(),preTime()和end()
begin($output, $environment)
该接口主要负责检测初始位置,当执行该接口时,就代表着检测开始。
preTime()
该接口主要是检测上一次代码执行时间
end()
该接口主要是检测总的执行时间

三、举例
  1. require "run_time_test.php";  
  2.   
  3. Run_Time_Test::begin(true);  
  4.   
  5. $a = "";  
  6. $b = "";  
  7. for($i=0; $i$i++){  
  8.     $a .= $i;   
  9. }  
  10.   
  11. Run_Time_Test::preTime();  
  12.   
  13. for($i=0; $i$i++){  
  14.     $b .= $i;   
  15. }  
  16.   
  17. Run_Time_Test::end();  

加载该工具类,同时设置检测起始位置,同时在代码中添加多个Run_Time_Test::preTime();检测每个阶段的代码执行效率,最后输出总的运行时间。

四、主要用途
可以在PHP的入口添加begin和输出处添加end,在需要测试效率处添加两个Run_Time_Test::preTime();进行检测,将执行结果记录到info log中。从而查看代码的执行效率,特别是一些算法执行过程中。
