当我们将AuthnetCIM.class.php类包含到控制器中时，我们有时会遇到错误。代码如下：
<?php
require_once 'include/AuthnetCIM.class.php';
include(CAPTCHA_ROOT.'recaptchalib.php');
// get a key at http://www.google.com/recaptcha/mailhide/apikey
$mailhide_pubkey = '6LfP_cESAAAAAKtGvePIIra7rB7sVAa6gd6nBaVO';
$mailhide_privkey = '6LfP_cESAAAAAIFyf6u3y2rQv0_B4zNA9VJLQei2';
class BrokerController extends AppController
{
public function init()
{
/* Initialize action controller here */
}
}
?>
我在打开和关闭php标签之前和之后都没有任何空格。
在initAction（）之后我有一个使用AuthnetCIM.class.php类的动作。
错误如下：
