(PECL eio >= 0.0.1dev)
eio_custom — Execute custom request like any other eio_* call.
eio_custom() executes custom function specified by execute processing it just like any other eio_* call.
Specifies the request function that should match the following prototype:
mixed execute(mixed data);
void callback(mixed data, mixed result);
The request priority: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or NULL. If NULL passed, pri internally is set to EIO_PRI_DEFAULT.
callback function is called when the request is done. It should match the following prototype:
void callback($data, $result);
Arbitrary variable passed to callback.
eio_custom() returns request resource on success or FALSE on error.
Example #1 eio_custom() example
<?php
/* Callback for the custom callback */
function my_custom_callback($data, $result) {
var_dump($data);
var_dump(count($result));
var_dump($result['data_modified']);
var_dump($result['result']);
}
/* The custom request */
function my_custom($data) {
var_dump($data);
$result = array(
'result' => 1001,
'data_modified' => "my custom data",
);
return $result;
}
$data = "my_custom_data";
$req = eio_custom("my_custom", EIO_PRI_DEFAULT, "my_custom_callback", $data);
var_dump($req);
eio_event_loop();
?>
The above example will output something similar to:
resource(4) of type (EIO Request Descriptor) string(14) "my_custom_data" string(14) "my_custom_data" int(2) string(14) "my custom data" int(1001)
