Esempi

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 */
?>

Il precedente esempio visualizzerà qualcosa simile a:

int(3)
int(0)
string(8) "nop data"
int(0)
string(10) "mkdir data"
