php get URL of current file directory

Might be an easy question for you, but I'm breaking my head over this one.

I have a php file that needs to know it's current directory url to be able to link to something relative to itself.

For example, currently I know to get the current directory path instead of the url. When I use this I get the path:

realpath(__DIR__)


result:

/Applications/MAMP/htdocs/mysite/dir1/dir2/dir3


But this would be my desired result:

http://localhost:8888/dir1/dir2/dir3


Note that this is not the location of the current page. The page calls a file from "http://localhost:8888/dir1/dir2/dir3/myfile.php"
And "myfile.php" has the script from above.

-- edit to elaborate more details --
Thanks for your answers. But I get that I need to add more detail.

$_SERVER['DOCUMENT_ROOT']

Use echo $_SERVER['PHP_SELF'];

echo $_SERVER['PHP_SELF'];

For example if the URL is http://localhost/~andy/test.php

http://localhost/~andy/test.php

The output would be:

/~andy/test.php

/~andy/test.php

That's enough to generate a relative URL.

If you want the directory your current script is running in - without the filename - use:

echo dirname($_SERVER['PHP_SELF']);

echo dirname($_SERVER['PHP_SELF']);

In the case above that will give you /~andy (without test.php at the end). See http://php.net/manual/en/function.dirname.php

/~andy

test.php

Please note that echo getcwd(); is not what you want, based on your question. That gives you the location on the filesystem/server (not the URL) that your script is running from. The directory the script is located in on the servers filesystem, and the URL, are 2 completely different things.

echo getcwd();

There is also a function to parse URL's built in to PHP: http://php.net/manual/en/function.parse-url.php

If your URL is like this: https://localhost.com/this/is/a/url

https://localhost.com/this/is/a/url

$_SERVER['DOCUMENT_ROOT'] - gives system path [/var/www/html/this/is/a/url]

$_SERVER['DOCUMENT_ROOT']

$_SERVER['PHP_SELF'] - gives the route of the current file (after the domain name) [/this/is/a/url]

$_SERVER['PHP_SELF']

$_SERVER['SERVER_NAME'] - gives the domain name [localhost.com]

$_SERVER['SERVER_NAME']

$_SERVER['HTTP_REFERER'] - gives the correct HTTP(S) protocol and domain name. [https://localhost.com]

$_SERVER['HTTP_REFERER']

If you would like to get the full url, you can do something like:

echo $_SERVER['HTTP_REFERER'] . $_SERVER['PHP_SELF'];

echo $_SERVER['HTTP_REFERER'] . $_SERVER['PHP_SELF'];

However, I do believe in this case, that all you need is the relative path.. and in that case you should only need to use $_SERVER['PHP_SELF'];

$_SERVER['PHP_SELF'];

Based on your question, I believe this will get you what your want:

$_SERVER['HTTP_HOST'] . substr($_SERVER['REQUEST_URI'], 0, strrpos($_SERVER['REQUEST_URI'], "/"));


Reference:

$_SERVER['HTTP_HOST']

$_SERVER['REQUEST_URI']

With the added substr() and strrpos() methods, you can strip the _myfile.php` off of the end to get the desired result:

substr()

strrpos()

http://localhost:8888/dir1/dir2/dir3

dirname($_SERVER['PHP_SELF']);

substr()

strpos()

I've found a solution here:
https://stackoverflow.com/a/1240574/7295693

This is the code I'll now be useing:

function get_current_file_url($Protocol='http://')
return $Protocol.$_SERVER['HTTP_HOST'].str_replace($_SERVER['DOCUMENT_ROOT'], '', realpath(__DIR__));
