Medidor De Velocidade De Conexão

zot · Agosto 22, 2005

Bem tava olhando na web e vi que alguns sites construido em PHP consegue medi a velocidade da minha conexão....

alguém tem ideia de como fazem isso....??

Por favor se alguém souber alguma coisa posta aqui...

Thanks...

Olá,

Não encontrei nada nem no manual e nem no google. O mas próximo que cheguei foi em um fórum onde um dos membros enviou o código abaixo e pediu para os outros testarem, mas não cheguei nem a ler o código. Da uma analizada e se funcionar mesmo me da um toque. Abs

<?php

/*** Bandwidth Tester 0.92 ***/

/* Please wait for 1.0 patiently! */

// How many bytes to test with. Mimimum=70. 128KB=131072. 1MB=1048576

$testsize = 131072;

header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past

header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

// always modified

header ("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1

header ("Pragma: no-cache"); // HTTP/1.0

header ("X-Notice: ");

header ("X-Notice: Bandwidth-Tester is freeware.");

header ("X-Notice: You may use it freely on your site.");

header ("X-Notice: Just don't remove this notice.");

header ("X-Notice: To get the source code, run this script ");

header ("X-Notice: with downloadme=1 in the query string.");

/* How does it work? The script generates a variable amount of random data

* sends it to the client and measures the time taken for transmission. The

* bandwidth is then calculated from the time using a simple algorithm.

*

* WARNING: This script can bog down your server - as absolutely NO

* optimization was used.

*

* This script is best run on the Zend PHP Engine, with Zend Optimizer.

* Any improvement in performance is not guaranteed with other

* PHP Engines.

*

* History:

* 0.9 - First public release

* 0.91 - Reduced the size of the timing code

* 0.92 - Reduced the size of the timing code even more

* Forecast:

* 0.921a - Adding a smaller test before the main to make results more accurate and to adjust test data according to first results

* 1.0 - Looking to adding optimization code

* 1.1 - Adding template support

* 1.2 - Adding web-based administration
