    Esempi

    Example #1 eio_poll() example

    <?php
    function res_cb($data, $result) {
    var_dump($data);
    var_dump($result);
    }

    eio_nop(EIO_PRI_DEFAULT, "res_cb", "1");
    eio_nop(EIO_PRI_DEFAULT, "res_cb", "2");
    eio_nop(EIO_PRI_DEFAULT, "res_cb", "3");

    while (    eio_nreqs()) {
    // Some specific IPC or so
    eio_poll();
    }
    ?>

    Il precedente esempio visualizzerà qualcosa simile a:

    string(1) "1"
int(0)
string(1) "3"
int(0)
string(1) "2"
int(0)
