示例 #1 eio_nreqs() 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()) {
eio_poll();
}
?>

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