Pinging Site??

[Anon]

Can i ping from one site to another to see if its online?
I want to check if a site is online, if the site isn't then i want the visitors to be guided to another.

Who can help me?

Thanks,

One way to do this is to try and fopen() the site.

$site_one = "http://www.mysite.com";
$site_two = "http://www.myothersite.com";

if(@fopen($site_one, "r")) {
Header("Location: $site_one");
} else {
Header("Location: $site_two");
}

.. although it's a bit dirty and probably slow.

probably slow

Sure, but if all you care about is "is this site up", just use fsockopen() to try to open a connection to port 80 on the machine, and you can then specify your own timeout.

<?

$query = fsockopen("123.456.789.01", 80, &$errno, &$errstr, 10);

if(!$query) {
echo "The site is up\n"; }

else {

echo("The site is down\n"; }
}
?>

Yes, but isn't the sense of the test reversed? The ! doesn't belong there, the way I read it.

Also, you might want to close the socket after you're done with it (if it does succeed.)

Thanks,

I will try this ASAP.
