make ping with PHP

[guif]

I would like to make a simple monitoring. I make this:

 

<?php
$ip = $_SERVER['127.0.0.1'];
exec("ping -n 4 $ip 2>&1", $output, $retval);
if ($retval != 0) { 
echo "no!"; 
} 
else 
{ 
echo "yes!"; }
?>

 

I use my internal IP: 127.0.0.1.

The result is: NO!

 

why???

[davidkierz]

exec("ping -n -c 4 $ip 2>&1", $output, $retval);

 

 

[guif]

not's run. The result is: no!

[guif]

I change this code and I put this:

 

IP: 10.140.206.123 (
<?php
$ping_ex = exec("ping -n 1 10.110.206.123", $ping_result, $pr);
if (count($ping_result) > 1){
echo "<img src=\"on.png\">";
} else{
echo "<img src=\"off.png\">";
}
?> )


IP: 127.0.0.1 (
<?php
$ping_ex = exec("ping -n 1 127.0.0.1", $ping_result, $pr);
if (count($ping_result) > 1){
echo "<img src=\"on.png\">";
} else{
echo "<img src=\"off.png\">";
}
?> )

 

In the first case the resulst are NO and the second case are YES.

But... the result is YES in two cases. Why???

[guif]

yeah!

finally I put this code:

 

<?php
$str = exec("ping -n 1 -w 1 100.100.100.100", $input, $result);
if ($result == 0){
echo "<img src=\"on.png\">";
}else{
echo "<img src=\"off.png\">";
}
?>

 

It's run correctly, but i would like to insert this code into a javascript function because I insert many times this PHP and the page is very hard to load.

I would like to insert a button:

 

<input type="submit" onClick="para();">

 

and when I press this button, the javascript runs.

Is it possible??

[Dathremar]

Well I would use ajax for that.. Think that will be a good solution

[guif]

did you know any tutorial, blog or any page to explain my question???

I took this snippet out of my ELC(External Link Checker), http://links.lamezz.com Type in the IP address to ping.

 

<?php
   $url = "127.0.0.1";
    $churl = @fopen($url,'r');
    if (!$churl && !empty($url)){
     echo "<br><center>The URL does not exist, or the server is down.</center>";
    }else{
     echo "<br><center>The URL does exist!</center>";
    }
?>

I use this code, but if I put many times the code for my different servers the refresh of the page is very slow...

Is it easy and possible accelerate my page?
