Examples
Example #1 polling STDIN using basic API
<?php
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, $fd, EV_READ | EV_PERSIST, "print_line", array($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($arg);
}
// print the line
echo event_buffer_read($buf, 4096);
}
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, $base);
event_buffer_enable($eb, EV_READ);
event_base_loop($base);
?>
