You will need to link to the file relative to the file that includes eventManager.php(Page A)
Change your code fromrequire_once('../includes/dbconn.inc');
您需要链接相对于包含文件的文件eventManager.php（页A）
从改变你的代码require_once('../includes/dbconn.inc');
Torequire_once('../mysite/php/includes/dbconn.inc');
到require_once('../mysite/php/includes/dbconn.inc');

The error pretty much explains what the problem is: you are trying to include a file that is not there.
该错误几乎解释了问题所在：您试图包含一个不存在的文件。
Try to use the full pathto the file, using realpath(), and use dirname(__FILE__)to get your current directory:
尝试使用文件的完整路径，使用realpath()和dirname(__FILE__)获取当前目录：
require_once(realpath(dirname(__FILE__) . '/../includes/dbconn.inc'));
回答by Csharls
this will work as well
这也能工作
require_once(realpath($_SERVER["DOCUMENT_ROOT"]) .'/mysite/php/includes/dbconn.inc');
回答by Hao Zonggang
set_include_path(get_include_path() . $_SERVER["DOCUMENT_ROOT"] . "/mysite/php/includes/");
set_include_path(get_include_path() . $_SERVER["DOCUMENT_ROOT"] . "/mysite/php/includes/");
Also this can help.See set_include_path()
这也可以帮助。见 set_include_path()

It says that the file C:\wamp\www\mysite\php\includes\dbconn.incdoesn't exist, so the error is, you're missing the file.
它说该文件C:\wamp\www\mysite\php\includes\dbconn.inc不存在，所以错误是，您丢失了该文件。
