 $.ajax({
               type: "POST",
               url: "ping1.php",

               data: $("#form1").serialize(), 

               success: function(data)  {
               $('#msg').html(data);

Php:

<?php




$ip=$_POST["ip"];

header('Content-Encoding: none;');

set_time_limit(0);

$handle = popen("ping -c 4 $ip", "r");

if (ob_get_level() == 0) ob_start();
while(!feof($handle)) {

$buffer = fread($handle,1024);
$buffer = trim(htmlspecialchars($buffer));

echo $buffer . "<br />";
echo str_pad('', 4096); 

ob_flush();
flush();
}

pclose($handle);
ob_end_flush();





?>

if i submit the form using php it will show the output in line by line..but i use jquery to submit the form means it will display the output but not in line by line.

First thing that comes to mind:

Make the PHP script that does the pinging (ping.php) write its results to, for example, ping_results.txt. Then, make an AJAX call to ping.php and immediatelty after execute a Javascript timeout that executes an AJAX function every 0.5 or 1 seconds, which opens ping_results.txt and …
