php做Ping的IP和連接埠測試

因為朋友說連接埠串連不上，特意試了一下用php做Ping測試，結果還是挺滿意的。

代碼和運行圖如下：（如果有大神改進就更好了）

<?php

$host = 'www.php100.com';

$port = '80';

$num = 3; //Ping次數

//擷取時間

function mt_f (){

list($usec,$sec) = explode(" ",microtime());

return ((float)$usec + (float)$sec); //微秒加秒

}

function ping_f($host,$port){

$time_s = mt_f();

$ip = gethostbyname($host);

$fp = @fsockopen($host,$port);

if(!$fp)

return 'reply time out!';

$get = "GET / HTTP/1.1\r\nHost:".$host."\r\nConnect:".$port."Close\r\n";

fputs($fp,$get);

fclose($fp);

$time_e = mt_f();

$time = $time_e - $time_s;

$time = ceil($time * 1000);

return 'reply from '.$ip.':'.$port.' time = '.$time.'ms<br />';

}

echo 'ping to '.$host.' ['.gethostbyname($host).'] with port:'.$port.' of data:<br />';

for($i = 0;$i < $num;$i++){

echo ping_f($host,$port);

//每次運行中間間隔1S

sleep(1);

//重新整理輸出緩衝

ob_flush();

flush();

}

?>
