Checking if a site is accessible?

Hello,
I've seen this done before, but not sure how it's done.

I have a data base of links, and I want to be able to loop through them and check if the links are working or dead.

could someone show me how this is done, or point me in the right direction?

thanks in advance for your time!

ok,,
well i've tried this:

<?php

$file = fopen ("http://www.remixwars.com/", "r");

if (!$file) {

echo "Site is Down";
exit;
} else {
echo "Site is Up";
exit;
}

fclose($file);

?>

which seems to work fine is the site is up, but if it's down i get this error:

Warning: fopen() [function.fopen]: php_network_getaddresses: getaddrinfo failed: No such host is known. in \remote.php on line 3


ideas anyone??

ah ok I seem to get the desired result when I add a @ infront of the fopen..

just incase anyone else needs this:

<?php

$file = @fopen ("http://www.remixwars.com/","r");

if (!$file) {

echo "Site is Down";
exit;
} else {
echo "Site is Up";
exit;
}

fclose($file);

?>

$file = @fopen("http://www.remixwars.com/", "r");

That'll sort that error out

haha,, not fast enough!
but thanks anyway :thumbsup:
