A PHP class to ping hosts.
There are a ton of different methods of pinging a server using PHP, and I've found most to be poorly documented or downright dangerous in their implementation.
Therefore, I've created this simple class, which incorporates the three most popular ping methods (exec() with the system's ping utility, fsockopen(), and socket_create()). Each method has its benefits and drawbacks, and may work better or worse on a particular system.
$ composer require geerlingguy/ping
This is a very simple class. Just create an instance, and run ping().
$host = 'www.example.com';
$ping = new \JJG\Ping($host);
$latency = $ping->ping();
if ($latency !== false) {
print 'Latency is ' . $latency . ' ms';
}
else {
print 'Host could not be reached.';
}You can also specify the ttl (maximum hops) and timeout when creating the instance:
$ttl = 128;
$timeout = 5;
$ping = new \JJG\Ping($host, $ttl, $timeout);...or using the setTtl() or setTimeout() methods:
$ping = new \JJG\Ping($host);
$ping->setTtl(128);
$ping->setTimeout(5);You can change the host using the setHost() method:
$ping = new \JJG\Ping($host);
...
