A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at /var/www/fbz/application/models/Content.php:268)
Filename: helpers/url_helper.php
貌似把前面的
<code>$logsession = $this->session->all_userdata(); </code>
这句去了也不会报错

因为在使用session前已经有输出了
一般是因为php文件?>结尾后有空格回车
或者使用了echo或print
