Hello all,

 

I've found a script wich can ping and echo a server status, the code is below:

<?php
// Function to check response time
function pingDomain($domain){
    $starttime = microtime(true);
    $file      = fsockopen ($domain, 80, $errno, $errstr, 10);
    $stoptime  = microtime(true);
    $status    = 0;

    if (!$file) $status = -1;  // Site is down
    else {
        fclose($file);
        $status = ($stoptime - $starttime) * 1000;
        $status = floor($status);
    }
    return $status;
}
?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">
<html>
<body>
      <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" name="domain">
        Domain name:
        <table>
          <tr><td><input name="domainname" type="text" ></td></tr>
          <tr><td><input type="submit" name="submitBtn" value="Ping domain"></td></tr>
        </table>  
      </form>
<?php    
    // Check whether the for was submitted
    if (isset($_POST['submitBtn'])){
        $domainbase = (isset($_POST['domainname'])) ? $_POST['domainname'] : '';
        $domainbase = str_replace("http://","",strtolower($domainbase));
        
        echo '<table>';

        $status = pingDomain($domainbase);
        if ($status != -1) echo "<tr><td>http://$domainbase is ALIVE ($status ms)</td><tr>";
        else               echo "<tr><td>http://$domainbase is DOWN</td><tr>";

         echo '</table>';
    }
?>

 

What I want is that I can use this script for give me the outcome of more servers. So I changed the form method to "get" to see the url wich is used. for example this:

http://www.mydomain.com/checkwebsitestatus.php?domainname=www.google.nl&submitBtn=Ping+domain

 

When I put this into the adresbar it does not give my a outcome.

 

Can somebody tell me how to fix this script so I can display multiple domains beneath eachothr like this for example

 

* http://www.google.nl is ALIVE (26 ms)

* http://www.yahoo.com is ALIVE (133 ms)

* http://www.klinkklareonzintoch.nl is DOWN

 

I hope somebody understands what I mean an can help me also.

oops...forgot to change that variable:

 

<?php

//Fill this in with the list of servers
$servers = array(
  'www.google.nl',
  'www.yahoo.com',
  'www.klinkklareonzintoch.nl',
);

// Function to check response time
function pingDomain($domain){
    $starttime = microtime(true);
    $file      = fsockopen ($domain, 80, $errno, $errstr, 10);
    $stoptime  = microtime(true);
    $status    = 0;

    if (!$file) $status = -1;  // Site is down
    else {
        fclose($file);
        $status = ($stoptime - $starttime) * 1000;
        $status = floor($status);
    }
    return $status;
}
?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "DTD/xhtml1-transitional.dtd">
<html>
<body>
  <table>
<?php    
  foreach($servers as $domainbase){
    $status = pingDomain($domainbase);
    if ($status != -1)
      echo "<tr><td>$domainbase is ALIVE ($status ms)</td><tr>";
    else
      echo "<tr><td>$domainbase is DOWN</td><tr>";
  }
?>
</table>
</body>
</html>

ok, now I have this :)

 

foreach($servers as $domainbase){

 

it seems to work, but goves me also this:

Is there a way to exclude the warnings?? I think it's part of the fsockopen function, but I really hope it can be fixed, because it looks like s**t on a website :)

 

line 13:

$file      = fsockopen ($domain, 80, $errno, $errstr, 10);

 

 

Warning: fsockopen() [function.fsockopen]: php_network_getaddresses: getaddrinfo failed: Name or service not known in /var/www/g35003/coldcharlie.nl/HTML/beta1/multi.php on line 13

 

Warning: fsockopen() [function.fsockopen]: unable to connect to www.klinkklareonzintoch.nl:80 (Unknown error) in /var/www/g35003/coldcharlie.nl/HTML/beta1/multi.php on line 13

 

www.google.nl is ALIVE (27 ms)

www.yahoo.com is ALIVE (125 ms)

www.klinkklareonzintoch.nl is DOWN

 

 

[edit]ahh, it was the same idea :)[/edit]

The errors would be because the sites do not exist, but that is what the function should find out so you can suppress the errors by using an @ symbol in front of the fsockopen();

 

Like so

 

@fsockopen ($domain, 80, $errno, $errstr, 10);
