PHP Netbeans 中的未知函数 - 如何抑制? [英] Unknown function in PHP Netbeans - how to suppress?

问题描述

由于我在 localhost 上开发但部署在其他地方，并且由于我不想强制我的网站位于 Windows 分区的根目录(当前为 F:\web_dev\htdocs)下，代码如下:

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

导致 Netbeans 发出警告:未知函数".

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

现在，我可以通过使用如下目录结构来解决这个问题:

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

F:\project_1  
F:\project_2  

代替

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

然后使用

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

但是这对最终用户安装我的网站的位置施加了限制.

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

目前最简单的方法是告诉 NetBeans 哪个本地目录对应于 $_SERVER['DOCUMENT_ROOT']，但我找不到相应的配置选项.我确定这是一个常见问题.有什么建议吗?

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?

更新:NetbBeans v7.0.1

Update: NetbBeans v7.0.1

推荐答案

只需将 /path/to/projXY/database/ 目录添加到项目的包含路径中.Netbeans 然后会在那里提取文件并将它们用作代码引用.

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.

依赖 $_SERVER['DOCUMENT_ROOT'] 通常是个坏主意.一方面，它消除了通过控制台/命令行运行部分应用程序的能力.

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.

您应该改为使用可配置的绝对路径来共享库，或者按照 布兰登的回答 并使用来自 __DIR__ (PHP 5.3) 或 dirname(__FILE__)

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__)
