function print_line($fd$events$arg)
{
    static 
$max_requests 0;

    
$max_requests++;

    if (
$max_requests == 10) {
        
// exit loop after 10 writes
        
event_base_loopexit($arg[1]);
    }

    
// print the line
    
echo  fgets($fd);
}

// create base and event
$base event_base_new();
$event event_new();

$fd STDIN;

// set event flags
event_set($event$fdEV_READ EV_PERSIST"print_line", array($event$base));
// set event base
event_base_set($event$base);

// enable event
event_add($event);
// start event loop
event_base_loop($base);

?>

Example #2 polling STDIN using buffered event API

<?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($buf4096);
}

function 
error_func($buf$what$arg)
{
    
// handle errors
}

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

event_buffer_base_set($eb$base);
event_buffer_enable($ebEV_READ);

event_base_loop($base);

?>
