Example #1 Using eio with libevent
<?php
function my_eio_poll($fd, $events, $arg) {
/* Some libevent regulation might go here .. */
if (eio_nreqs()) {
eio_poll(
}
/* .. and here */
}
function my_res_cb($d, $r) {
var_dump($r var_dump($d
}
$base = event_base_new(
$event = event_new(
$fd = eio_get_event_stream(
var_dump($fd
eio_nop(EIO_PRI_DEFAULT, "my_res_cb", "nop data"
eio_mkdir("/tmp/abc-eio-temp", 0750, EIO_PRI_DEFAULT, "my_res_cb", "mkdir data"
/* some other eio_* calls here ... */
// set event flags
event_set($event, $fd, EV_READ /*| EV_PERSIST*/, "my_eio_poll", array($event, $base)
// set event base
event_base_set($event, $base
// enable event
event_add($event
// start event loop
event_base_loop($base
/* The same will be available via buffered libevent interface */
?>
The above example will output something similar to:
int(3)
int(0)
string(8) "nop data"
int(0)
string(10) "mkdir data"
