启用URL重写时，PHP file_exists（）无法检查文件是否存在？

Question

in Zend FW:

file_exists('xx/xxx/xxxx.jpg');

returned 1, but xx/xxx/xxxx.jpg is not file or directory.

it's an error page returned by Zend FW. because it's not a file or valid url

how can I check file existence?

Answer 1

file_exists checks whether a file or directory exists. Try use is_file
