Make a ping test with PHP
The problem with fsockopen is you have to known the destination port.
A real ping function could be :
<?php
function php_ping($url) {
$addr=parse_url($url);
$host=$addr['host'];
exec("ping -c 1 -w 1 $host", $list);
if (strpos($list[4],"1 received")>0) {
return true ;
}
return false;
}
?>
But if your router refuse the ping ... the result will be always false > you may test both
(fsockopen and ping)
