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.

In response to the comment on my previous post. Since your post is pretty high up on search engines, I hope it helps somebody to get the path from web root:. 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. Just read the article above, it explains what to do. Thank you very much. I'll be studying this page for a while until I get it right.

You should write a book. Very well explained and extremely helpful. Thank You for sharing your knowledge. What would you recommend as a work around? I added another section to the article, in this exact case. If the answer would not satisfy you, please share your doubts. Thank you for helping me to make the site better! Hi, We have an application hosted in IIS. This application has file upload control. When i chose a file to upload from a folder it takes the full path along with file name and this full path is considered as file name in the system.
Some times it exceedes max file name length and throws an error. This feature was working file before. What if you need to handle file uploads from MS IE? There is a problem reading non-Latin characters in the file name if the locale is not configured correctly. On windows systems, filenames are case-insensitive. With realpath you can "extend" this functionality. Because of filename gets "file. Try Long Path Tool as it can remove any problems that you might have.

Caution pathinfo is locale aware, so for it to parse a path containing multibyte characters correctly, the matching locale must be set using the setlocale function. Parameters path The path to be parsed. Return Values If the flags parameter is not passed, an associative array containing the following elements is returned: dirname , basename , extension if any , and filename. Note: pathinfo is locale aware, so for it to parse a path containing multibyte characters correctly, the matching locale must be set using the setlocale function.
If a file has more than one 'file extension' seperated by periods , the last one will be returned. Note that this function seems to just perform string operations, and will work even on a non-existent path, e. Checked with version 5. Here is a simple function that gets the extension of a file.
