出现以下错误提示：
Warning: Cannot modify header information – headers already sent by (output started at D:\amp\www\htdocs\data\config.php:1) in D:\amp\www\htdocs\includes\cls_session.php on line 116
Warning: Cannot modify header information – headers already sent by (output started at D:\amp\www\htdocs\data\config.php:1) in D:\amp\www\htdocs\includes\cls_template.php on line 58
打开php.ini,把 output_buffering 默认的 Off 设为4096就OK了。
修改完PHP.ini配置文件后，一定要重启PHP才能生效。
