__FILE__ to

[P3t3r]

I'd like to make a file that recognizes its own relative path. So if the file is named /var/www/vhosts/mysite.com/httpdocs/dirname/folder1/folder2/test.php, then it should create a variable $relpath="folder1/folder2/test.php". Of course substr(__FILE__,36) and then removing the dirname works, but that's not quite dynamic. What is the 'correct' way to do this?

 

Shortest code (in bytes) preferred. Thanks in advance!

define("_ROOT_", "/var/www/vhosts/mysite.com/httpdocs/dirname/");
$relpath= _ROOT_ . "folder1/folder2/test.php"

Your much better off using absolute paths anyways.

Ok, I'll be more specific. I have folders

/var/www/vhosts/mysite.com/httpdocs/dirname/folder1/folder2/test.php,

/var/www/vhosts/mysite.com/httpdocs/dirname2/folder3/folder4/test.php,

/var/www/vhosts/mysite.com/httpdocs/dirname3/folder5/folder6/test.php...

 

and I'd like to extract the /dirname/ from it (more specificly replace them all with /folder0/). I could make a list of all possible names for httpdocs/httpsdocs/httpd/... and math the part after that, but I guess there must be a better way?

you can use the following

 

echo dirname(__FILE__);

 

hope its what you wanted...

Set up a root the root path, then use str_replace to remove it from the __FILE__ and you will get the path relative to the root:

 

<?php
$root = '/your/root/folder';
$relative = str_replace($root, '', __FILE__);
?>

Set up a root the root path, then use str_replace to remove it from the __FILE__ and you will get the path relative to the root:

 

<?php
$root = '/your/root/folder';
$relative = str_replace($root, '', __FILE__);
?>

Is there a way to find the root path dynamically? My host seems to swap servers regularly. Or would this consume too much execution time?

The only thing I can come up with is $_SERVER['DOCUMENT_ROOT'] but I am not sure how reliable that is.

[rajivgonsalves]

you should do

 

$relative = str_replace($_SERVER['DOCUMENT_ROOT'], '', __FILE__);
