Find htdocs path, no matter where file is stored

How can I find my htdocs directory.

When I execute the following command:

echo  dirname(__FILE__);

I get the following output:

/var/www/myexample.com/htdocs/required/css

I want to find path till /htdocs, but I don't want to hard-code the things

I know I can use:

dirname(dirnam开发者_开发百科e(dirname(__FILE__)))

But, that will work if the current file is in "css" directory. If I will move to some other directory inside "css" directory, then it will not work.

Any solution for this?

If you are running Apache, the

$_SERVER["DOCUMENT_ROOT"]

environment variable should give you the current document root. See $_SERVER in the manual.

On most setups $_SERVER['DOCUMENT_ROOT'] should give you what you want.

I use this script to find them all should $_SERVER['document_root'] be unavailable, including htdocs.

<?php
$scriptRelativeName = substr($_SERVER['SCRIPT_FILENAME'], strripos($_SERVER['SCRIPT_FILENAME'], $_SERVER['SCRIPT_NAME']));  //get relative name of script case sensitive from script_filename provided by filesystem by getting position of script_name in url and substracting the filesystem path
$scriptRelativePath = substr($scriptRelativeName , 0, strrpos($scriptRelativeName, "/"));  //get relative path by subtracting everything after the last slash in the relative name
$rootFolder = str_ireplace($scriptRelativeName, "", $_SERVER['SCRIPT_FILENAME']);  //subtract the scriptrelativename from script_filename to get the root folder
echo "Relative Script Name: " . $scriptRelativeName . "<br>";
echo "Relative Script Path: " . $scriptRelativePath . "<br>";
echo "Htdocs/Root Folder Path: " . $rootFolder . "<br>";
?>
