Get absolute path of a relative path of a XML file

Question

Is it possible to guess the absolute path of a relative path that I have specified for loading a XML file? This is my coding:

$strXML = __DIR__ . "/../xml/file.xml";
$xmlFile = simplexml_load_file($strXML);

$strPath = fullPathFunction($xmlFile);  //Desired function

@Phil I'm already using realpath() function, but when I use it, I'm just geting /home/user/public_html but my expected result is /home/user/public_html/xml/file.xml — Alberto Muñoz Sánchez

Try $strXML = __DIR__ . '/../xml/file.xml'; assuming the path is relative to your .php script — Phil

@Phil I think we are near. __DIR__ is geting the path to my .php file, so it gets /home/user/public_html/php but my .xml file is inside /home/user/public_html/xml directory — Alberto Muñoz Sánchez

Yes, I realise that. That is why the path /../xml/file.xml is appended to __DIR__. If __DIR__ is /home/user/public_html/php, then /home/user/public_html/php/../xml/file.xml will resolve (via realpath()) to /home/user/public_html/xml/file.xml. If you're now using __DIR__, please update the code in your question — Phil

You can use realpath function:

$strXML = "../xml/file.xml";
$xmlFile = simplexml_load_file($strXML);

$strPath = realpath($strXML);

That's not sense. realpath would return the folder that contains the file, in this case /home/user/public_html/xml, please, print the var_dump of $file are used as argument in realpath function.

update: added the filename to complete the expected result.

The result is string(15) "../xml/file.xml"
