Checking If EXTERNAL website is online..

[mesh]

hi, im looking for a script that will check an external website, every so often say 30 minutes. now i no there is one as a guy on another forum mentioned he used one. But can not remember what its called.

Can some one point me into a direction on where i should be looking or searching for, or how i can get hold of?

He mentioned it to be in a PHP script language.

Cheers

Do you mean checking if the website exists?

yep

[Mr. Tech]

Try this code:

<?php
function check($sitesurl) {
if (@file($sitesurl)) {
$file = "true";
} else {
$file = "false";
}
return $file;
}

if (check("http://www.webmaster-resources101.com") == "true") {
print "It exists!";
} else {
print "It don't exist!";
}
?>
