PHP Redirect unless site down
Posted: Sat Feb 12, 2011 8:39 pm
(for those who have been asking)
I created this because I am redirecting all traffic from port 80 to port 8080. Port 8080 runs a newLisp web server and DragonFly, but it could be running anything.
Sometimes, for whatever reason, my ISP decides to kill the newLisp process.
So, this redirects people to a "maint.html" page when that happens.
I hope this is as useful for everyone else as it has been for me.
Plus, it's super fast and simple PHP code.

Code: Select all
<?php
$site = "www.mysite.com";
$port = 8080;
$fp = fsockopen($site,$port,$errno,$errstr,10);
if(!$fp)
{
$fd = fopen("maint.html", r);
$content = fread($fd, filesize("maint.html"));
fclose($fd);
echo $content;
}
else{
header("Location: http://www.mysite.com:8080");
//echo "Connect was successful - no errors on Port ".$port." at ".$site;
fclose($fp);
exit;
}
//
?>
