Description: 测试php脚本性能的框架(Framework to benchmark PHP scripts or function calls. )
Download: Benchmark pear
下载文件后解压文件目录结构如下
运行timer_example.php显示效果图如下
主要函数:
$timer->start() 开始标记 相当于 $timer->setMarker("start')
测试 is_file与file_exists性能对比$timer->setMarker('mark'); 标记 返回页面时此处标记到上一个标记之间的 时间、百分比 $timer->stop() 结束标记 相当于 $timer->setMarker('stop')
$timer->display(); 输出到页面
<?php require 'Benchmark/Timer.php'; $filename='C:\Users\baixinxing\Desktop\Benchmark-1.2.9\Benchmark-1.2.9\README'; $timer = new Benchmark_Timer(); $timer->start(); for ($index = 0; $index < 10000; $index++) { //判断给定文件名是否为一个正常的文件 is_file($filename); } $timer->setMarker('is_file'); for ($index = 0; $index < 10000; $index++) { //检查文件或目录是否存在 file_exists($filename); } $timer->setMarker('file_exists'); $timer->stop(); $timer->display();Salin selepas log masuk

function get() 返回函数每次执行时间和平均时间
