PHP测试网速

一段测试你网络速度的PHP

<?php

//$file = fopen('abc.txt','w');
//for($i=0;$i<170400;$i++) fwrite($file,'helloworld');
//fclose($file);

$data = file_get_contents('abc.txt');
$fsize = filesize("abc.txt")/1024;

$start = gettime();

echo $data;

$end = gettime();

$cs = ($end['0']+$end['1']) - ($start['0']+$start['1']);

$speed = round(($fsize / $cs),2);

echo "
network: ".$speed." KB/sec.";


function gettime()
{
return explode(" ",microtime()); 
}
