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(); } ?>
The above example will output something similar to:
string(1) "1" int(0) string(1) "3" int(0) string(1) "2" int(0)
