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. Her

Answer 1

Create a constant with absolute path to the root by using define in ShowInfo.php:

define('ROOTPATH', __DIR__);

Or PHP <= 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')) {
  // ...
}
