On timeout the error callback is executed. This can be very valuable if you wanted to monitor inactivity on a socket.

You also need to use event_buffer_enable if you wanted to re-use the event listener.

Example:

<?php
function print_line($buf, $arg)
{
    static
$max_requests;

   
$max_requests++;

    if (
$max_requests == 10) {
       
event_base_loopexit($arg);
    }

   
// print the line
   
echo event_buffer_read($buf, 4096);
}

function
error_func($buf, $what, $arg)
{
   
// If this was a read timeout
   
if ($what == (EVBUFFER_READ | EVBUFFER_TIMEOUT)) {
        echo
'5 seconds of inactivity'."\n";

       
// Control timeout features
        //    Could ping the client, or even disconnect the client if you really wanted to.
        //    --- ETC

        // Restart our event loop on this buffer
       
event_buffer_enable($buf, EV_READ);
    }
}

$base = event_base_new();
$eb = event_buffer_new(STDIN, "print_line", NULL, "error_func", $base);

// Timeout after 5 seconds of inactivity
event_buffer_timeout_set($eb, 5, NULL);
event_buffer_base_set($eb, $base);
event_buffer_enable($eb, EV_READ);

event_base_loop($base);

?>
