范例

Example #1 Using eio with libevent

<?phpfunction 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($fd);eio_nop(EIO_PRI_DEFAULT, "my_res_cb", "nop data");eio_mkdir("/tmp/abc-eio-temp", 0750, EIO_PRI_DEFAULT, "my_res_cb", "mkdir data");/* some other eio_* calls here ... */// set event flagsevent_set($event, $fd, EV_READ /*| EV_PERSIST*/, "my_eio_poll", array($event, $base));// set event base event_base_set($event, $base);// enable eventevent_add($event);// start event loopevent_base_loop($base);/* The same will be available via buffered libevent interface */?>

以上例程的输出类似于：

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