Send an ICMP ping and place the result in an array

This function sends an ICMP ping request to a host by name or IP address and returns connection information as an array.

$host: A URI web address name (such as example.com) or an IP address (such as 172.16.254.1). If a URI is provided the function will attempt to resolve it to an IP address by DNS.

A key/value array of connection status information:

<?
  $res=ping("example.com");
?>

Sample result if no connection is established:

[$res] = Array (
(int) [response] => -1
(string) [host] => example.com
(string) [ip] => 0.0.0.0
(int) [seq] => 0
) 

Sample result if a connection is successful:

[$res] = Array (
(int) [response] => 1
(int) [time] => 25
(string) [host] => example.com
(string) [ip] => 93.184.216.34
(int) [seq] => 2
)
