PHP Netbeans中的未知功能 - 如何抑制？

Question

Since I develop on localhost but deploy elsewhere, and since I don't want to have to force my sites to be under a Windows partition's root directory (currently F:\web_dev\htdocs), code like this:

require_once($_SERVER['DOCUMENT_ROOT'] . '/projXY/database/database_common.php');
OdbcExec($sql); // defined in the file above

causes Netbeans to issue a "Warning: unknown function".

Now, I could get round this by using a directory structure like :

F:\project_1  
F:\project_2  

instead of

F:\web_dev_htdocs\project_1  
F:\web_dev_htdocs\project_2  

and then using

require_once('/database/database_common.php');

BUT that imposes constraints on where the end-user an install my site.

Simplest by far would be to tell NetBeans which local directory corresponds to $_SERVER['DOCUMENT_ROOT'], but I can't find a configuration option for that. I am sure this is a common problem. Any suggestions?

Answer 1

Simply add the /path/to/projXY/database/ directory to your project's include path. Netbeans will then pick up the files there and use them as code references.

Addendum

Relying on $_SERVER['DOCUMENT_ROOT'] is generally a bad idea. For one, it eliminates the ability to run parts of your application via the console / command line.

You should instead either use configurable, absolute paths to shared libraries or do as in Brandon's answer and use a relative path from __DIR__ (PHP 5.3) or dirname(__FILE__)
