PHP absolute path to root

Question

I can t believe PHP doesn t have an easy solution for this simple matter  ASP NET has a   sign that takes care of this issue and starts everything from the root level  Here s my problem  localhost MySite    -- gt Admin       -- Edit php    -- gt Class       -- class EditInfo php    -- gt Texts       -- MyInfo txt    --ShowInfo php  Inside class EditInfo php I am accessing MyInfo txt so I defined a relative path  quot    Texts MyInfo txt quot   Then I created an object of EditInfo in Admin Edit php and accessed Texts MyInfo txt - it worked fine  But now I have to create an object of EditInfo in ShowInfo php and access Texts MyInfo txt and here s the problem that occurs  As I am using a relative path in my class  whenever I am creating an objEditInfo and trying to access MyInfo txt I am getting  quot File doesn t exist quot  error  Now I am looking for something that s equivalent to  quot   Texts MyInfo txt quot  from ASP NET  Is there anything similar to that out there    Or do I have to set the path with some if else condition   UPDATE  I used   SERVER  DOCUMENT ROOT    I was using a subfolder where my actual website was  So I had to use   SERVER  DOCUMENT ROOT    quot  mySite quot   amp  then adding rest of the address   quot  Texts MyInfo php quot   to it

You can access the   SERVER  DOCUMENT ROOT   variable     lt  php      path     SERVER  DOCUMENT ROOT        path      subdir1 yourdocument txt     gt

This is my way to find the rootstart  Create at ROOT start a file with name mainpath php  lt  php     DEFINE ROOTPATH  check data exist    quot  quot      i surf   0      looking for mainpath php at the aktiv folder or higher folder  while   file exists  check data exist  quot mainpath php quot         check data exist     quot     quot       i surf         max 7 folder deep   if   i surf    7        return false         define  quot MAINPATH quot     check data exist    check data exist    quot  quot        gt   For me is that the best and easiest way to find them

In PHP there is a global variable containing various details related to the server  It s called   SERVER  It contains also the root      SERVER  DOCUMENT ROOT     The only problem is that the entries in this variable are provided by the web server and there is no guarantee that all web servers offer them

use dirname   FILE    in a global configuration file

The best way to do this given your setup is to define a constant describing the root path of your site  You can create a file config php at the root of your application    lt  php  define  SITE ROOT   dirname   FILE        file path   SITE ROOT     Texts MyInfo txt      gt    Then include config php in each entry point script and reference SITE ROOT in your code rather than giving a relative path

The best way Using dirname    Because SERVER  DOCUMENT ROOT   not working all servers  and also return server running path     root   dirname    FILE        root     DIR      filePath   realpath dirname   FILE        rootPath   realpath   SERVER  DOCUMENT ROOT       htmlPath   str replace  root       filePath

It always best to start any custom PHP project with a bootstrap file where you define the most commonly used paths as constants  based on values extracted from   SERVER  It should make migrating your projects or parts of your project to another server or to another directory on the server a hell of a lot easier   This is how I define my root paths    define  LOCAL PATH ROOT     SERVER  DOCUMENT ROOT     define  HTTP PATH ROOT   isset   SERVER  HTTP HOST        SERVER  HTTP HOST      isset   SERVER  SERVER NAME        SERVER  SERVER NAME       UNKNOWN        The path LOCAL PATH ROOT is the document root  The path HTTP PATH ROOT is the equivalent when accessing the same path via HTTP   At that point  converting any local path to an HTTP path can be done with the following code    str replace LOCAL PATH ROOT  RELATIVE PATH ROOT   my path    If you want to ensure compatibility with Windows based servers  you ll need to replace the directory seperator with a URL seperator as well    str replace LOCAL PATH ROOT  RELATIVE PATH ROOT  str replace DIRECTORY SEPARATOR        my path     Here s the full bootstrap code that I m using for the PHP PowerTools boilerplate    defined  LOCAL

Create a constant with absolute path to the root by using define in ShowInfo php   define  ROOTPATH     DIR       Or PHP  lt   5 3  define  ROOTPATH   dirname   FILE        Now use it   if  file exists ROOTPATH   Texts MyInfo txt                   Or use the DOCUMENT ROOT defined in   SERVER   if  file exists   SERVER  DOCUMENT ROOT     Texts MyInfo txt
