被解释为

因为我是新人，所以我不是很好。我不得不说我在WAMP下运行我的应用程序。它可能是微不足道的，但我不能得到它。

我甚至在autoload.php文件中包含了所有模块，如下所示：

$autoload['model'] = array(
'm_user',
'm_user_online',
'm_content_category',
'm_content',
'm_nation',
'm_mail',
'm_message',
'm_feedback',
'm_photo',
'm_tour',
'm_tour_rate',
'm_tour_departure',
'm_tour_departure_rate',
'm_tour_itinerary',
'm_tour_category',
'm_tour_activity',
'm_tour_destination',
'm_tour_tripnote',
'm_tour_request',
'm_visa',
'm_visa_tips',
'm_question',
'm_hotel',
'm_room',
'm_room_rate',
'm_album_category',
'm_album',
'm_tour_option_category'

Answer 1

根据评论：

您的第一块PHP出现在HTML视图中 - 包含屏幕截图的好主意！这表明它没有被解析为PHP，而是被解析为HTML，所以我会检查一下<?php是否出现在开头。
