This example shows how to obtain information about all devices and services. It starts an infinite loop (use CLI), and if any of available devices or services are found, the proper callback function will be invoked.

Example #1 Search for all UPnP devices and services.

  <?php

 
 function  device_proxy_available_cb ( $proxy ,  $arg )
{
     $info  =  gupnp_device_info_get ( $proxy );

     $type  =  $info [ 'device_type' ];
     $location  =  $info [ 'location' ];

     printf ( "Device available:\n" );
     printf ( "\ttype:     %s\n" ,  $type );
     printf ( "\tlocation: %s\n" ,  $location );
}

 
 function  service_proxy_available_cb ( $proxy ,  $arg )
{
     $info  =  gupnp_service_info_get ( $proxy );

     $type  =  $info [ 'service_type' ];
     $location  =  $info [ 'location' ];

     printf ( "Service available:\n" );
     printf ( "\ttype:     %s\n" ,  $type );
     printf ( "\tlocation: %s\n" ,  $location );
}

 
 $context  =  gupnp_context_new ();
if (! $context ) {
     printf ( "Error creating the GUPnP context\n" );
    exit(- 1 );
}

 
 $cp  =  gupnp_control_point_new ( $context ,  "ssdp:all" );

 
 gupnp_control_point_callback_set ( $cp , 
     GUPNP_SIGNAL_DEVICE_PROXY_AVAILABLE ,  'device_proxy_available_cb' );
 gupnp_control_point_callback_set ( $cp , 
     GUPNP_SIGNAL_SERVICE_PROXY_AVAILABLE ,  'service_proxy_available_cb' );

 
 gupnp_control_point_browse_start ( $cp );
