//======== Simple PHP code sample ==========//

/*
* This example requires allow_url_fopen to be enabled in php.ini.
* If it is not enabled, file_get_contents()
* will return an empty result.
*
* We recommend that you use port 5567 instead of port 80, but your
* firewall will probably block access to this port (see FAQ for more
* details):
* $url = http://nettyhost.com/smsapi/TR/sendmsg.aspx?;
*
* Please note that this is only for illustrative purposes,
* we strongly recommend that you use our comprehensive example
