radius_get_attr

Extracts an attribute

&reftitle.description; `mixed` `radius_get_attr` `resource` `radius_handle`

Like Radius requests, each response may contain zero or more attributes. After a response has been received successfully by `radius_send_request`, its attributes can be extracted one by one using `radius_get_attr`. Each time `radius_get_attr` is called, it gets the next attribute from the current response.

&reftitle.parameters;

&radius.parameter.handle;
&reftitle.returnvalues;

Returns an associative array containing the attribute-type and the data, or error number <= 0.

### `radius_get_attr` example

    <?php
    while ($resa = radius_get_attr($res)) {

        if (!is_array($resa)) {
            printf("Error getting attribute: %s\n",  radius_strerror($res));
            exit;
        }

        $attr = $resa['attr'];
        $data = $resa['data'];
        printf("Got Attr:%d %d Bytes %s\n", $attr, strlen($data), bin2hex($data));
    }
    ?>
