Getting the URL path to the directory of a file (PHP)

Question

Hi
I have a php file at, say, localhost/foo/foo/bar.php
which includes a file at localhost/foo/included.php
I need to be able to get "localhost/foo/" as a string inside included.php
If, instead of localhost/foo/foo/bar.php, it's localhost/big/burpy/lolz/here.php (still including included.php) I still need to get "localhost/foo/"
So, I need the path of the included file and not the one that the client requested.

I know when I see the solution I'm going to feel like a doofus, but it just escapes me at the moment. Help please? thanks :)

Answer 1

Inside your included file:

$yourdir = dirname(__FILE__);

or if you're using PHP 5.3.x:

$yourdir = __DIR__;

Get the document root from

// contains the document root, e.g. C:\xampp\htdocs
$docRoot = realpath($_SERVER['DOCUMENT_ROOT']);
// strip drive letter if found
if(strpos($docRoot, ':') === 1) $docRoot = substr($docRoot, 2);

// directory of included file, e.g. C:\xampp\htdocs\include
$dirInclude = realpath(dirname(__FILE__));
// strip drive letter if found
if(strpos($dirInclude, ':') === 1) $dirInclude = substr($dirInclude, 2);

// find the document root
$rootPos = strpos($dirInclude, $docRoot);
// if the path really starts with the document root
if($rootPos === 0){
    // example: \xampp\htdocs\include
    $visibleDir = substr($rootPos, $);
    // convert backslashes to slashes and strip drive letter
    $webPath = str_replace('\\', '/', $visibleDir);
    // yields: http://localhost/include
    echo 'http://localhost' . $webPath;
}
else{
   // included file was outside the webroot, nothing to do...
}

<?php
    $level = 2;
    $path = dirname($_SERVER["PHP_SELF"]);
    while( substr_count($path,"/") > $level ){
        $path = dirname($path);
    }
    echo $path;
?>

Answer 3

The steps for this are:

1. Use dirname(__FILE__) to get the folder of the include file.

2. Get the server root using $_SERVER['DOCUMENT_ROOT']

3. Remove the document root from the include folder to get the relative include folder

4. Obtain the server url

5. Append the relative include folder to the server url

Answer 4

I figured it out myself:

$realpath=str_replace('\\', '/', dirname(__FILE__));
$whatIwanted=substr_replace(str_replace($_SERVER['DOCUMENT_ROOT'], '', $realpath), "", -6));

There we go :) thanks for the help guys
