Solution to include file error in PHP script

Often when the php page uses include, require, require_once to include some pages in other locations, errors will occur, such as the page is not found, or permissions are not allowed, etc., which can be eliminated according to the following methods

1. When an error similar to "File not found" occurs, check whether the location of the include file is correct. The following is the original quote from the PHP manual page:

Files for including are first looked in include_path relative to the current working directory and then in the directory of the current script. E.g. if your include_path is libraries, current working directory is /www/, you included include/a.php and there is include "b.php" in that file, b.php is first looked in /www/libraries/ and then in /www/include/. If filename begins with ./ or ../, it is looked only in include_path relative to the current working directory.

2. When an error similar to permission deny occurs When, use the following methods to exclude

a) Check whether the read permission of the included file is turned on

b) Check whether the x permission of each directory on the path of the included file is turned on. Permissions determine whether the directory can be browsed.
