Server Status Checker

[Joshua F]

I am trying to make a Server Status checker that uses a image to tell if it is online or not. I also am trying to make it so you can the URL as a image code(EX: Http://domain.com/statuscheck.php?ip=google.com&port=80). What I'm trying to say it, that if you do like <img src="Http://domain.com/statuscheck.php?ip=google.com&port=80"> it would go to my site, use the php script, and then have the image Online or Offline, were the <img> code was posted.

 

Here's my code Im trying to make it from.

<?php
$ip="{$_GET['ip']}";
$port="{$_GET['port']}";
if(!$sock=@fsockopen($ip,"$port", $num, $error, 5)) {
Header('Content-type: image/png');
echo"<img src='images/offline.png'>";
} else {
Header('Content-type: image/png');
echo"<img src='images/online.png'>";
}
?>

An HTML <img> tag is not valid image file data. You should use readfile. Like so:

 

<?php
$ip="{$_GET['ip']}";
$port="{$_GET['port']}";
header('Content-type: image/png');
if(!$sock=@fsockopen($ip,"$port", $num, $error, 5)) {
readfile('image/offline.png');
} else {
readfile('image/online.png');
}
?>

readfile('image/offline.png');
} else {
readfile('image/online.png');
}
?>

 

So lets say I posted a Image BBCode with this in it

[img=http://domain.com/statuscheck.php?ip=google.com&port=80]

It would put the online/offline image wherever I put that code right?

Try it and find out.

It works, but would you know how to make it so if the Server is offline, it doesn't take any longer to load. That could cause some problems if someone posted it on something.

 

Online

Offline

 

Look how much longer it takes for the Offline image to load.

 

Edit: Also, if this is used a lot, would it eat up Monthly Bandwidth?

Of course it will take longer for it to load if the server is offline.  The fsocketopen() will have to wait for the timeout to expire.

Alright, just checking to see if there was a way to make it load faster. But do you know if it will eat up alot of Bandwidth?
