So I need a mechanism that will work irrespective of whether the application server will unpak the WAR or not so that web application can read that file I think your second solution won't work because I am not using the SuppliedFile. Hendy Irawan Hendy Irawan Daniel Daniel 11 1 1 bronze badge.

Although technically absolute starting from a slash , this path is essentially relative to the calling script, because if the calling script will be moved into another directory, it won't find the configuration file anymore. This is why it is recommended to use a single entry point for your application. Or - as in our case - two entry points, one for web requests and one for console commands.

So for our fictional application we would have three files - an entry point for the web front, an entry point for console applications and a bootstrap file:. From now on we can use it to build absolute paths starting from the root directory as long as our scripts are called through the entry point either web or console one :. Of course, both entry points should implement a sort of resolver to call all other pages and console scripts but that's slightly out of scope of this article.

There are may hepful commands and constants in PHP to ease the path interpolation. Some of them are:. I am the only person to hold a gold badge in , and on Stack Overflow and I am eager to show the right way for PHP developers.

DIR works well for including files in scripts. But for pointing to images or for URL generation, it doesn't work since you need a web root. Here an example:.

On linux, on windows, on apache or nginx, with PHP backend or node. Sometimes the project path is different between local development and live deployment. In this case it's helpful to have the path from web root to script if absolute paths from web root are used. And yes, relative urls just shouldn't be used at all. All local urls should be written as absolute paths, i. Great introduction, but doesn't help with the confusions introduced by require or include.

I don't think I will ever completely understand what happens in a chain of include files to the current directory and whether the current directory is used by include directives when they interpret their path argument. And that's before we consider the effects of the Include Path! Hey, I want to access a file located in a different folder. The file is called config. When i require it in another file called tables.
