这是我用来跟踪电子邮件打开率的页面这是一个 php 重定向到 gif 文件
问题是，我使用相同的帐户在GA中创建了两个campagin，它仅适用于第一个帐户，这是我的设置问题吗？谢谢

使用Google Analytics进行像素跟踪的代码看起来不错，但如果您更改参数，则可能会有所不同。请注意对请求进行 URL 编码。
您可以使用以下http_build_query结合使用 URL 编码和参数换行：
$data['utmac'] = 'UA-2202604-2';
$data['utmhn'] = 'mywebsite.com';
...
$url = 'http://www.google-analytics.com/__utm.gif?' . http_build_query($data, '', '&');
$handle = fopen($url, "r");
$test = fgets($handle);
fclose($handle);
