How can i get the absolute path for a file based on the fid? Sorry if this is a repeat, I did a search but was unable to find the answer.
Drupal 7
This is a two part process, using file_load() and file_create_url()
First, you need to turn the $fid into a Drupal URI:
$file = file_load($fid);
$uri = $file->uri;
Now, you can turn this into a URL
$url = file_create_url($uri);
file_create_url() always creates an absolute URL, either using the global $base_path that you have defined, or using the one that Drupal guessed during bootstrap.

1I am surprised you have to load the file just to get the path, seems like a waste of resources.– RussFeb 28 '14 at 3:55

2@Russ It's loading the file object, not the file itself. You could also do a db_query to get the uri, but I try to use the API as much as possible.– mpdonadio ♦Feb 28 '14 at 4:05

Thanks, I figured that, just thought there would be a clean function that could return it in one step. Maybe something to consider in drupal 8.– RussFeb 28 '14 at 13:21

2In your example you have 'field_load($fid)', it should be 'file_load($fid)'. Sep 8 '18 at 20:47

2@SteveMulvihill Wow, nice catch. Four+ years and 33 votes, and nobody noticed that.– mpdonadio ♦Sep 8 '18 at 21:42
Drupal 8
$file = \Drupal\file\Entity\File::load($file_id);
$uri = $file->getFileUri();
$url = \Drupal\Core\Url::fromUri(file_create_url($uri))->toString();

It works also only by calling file_create_url($uri); which is already returning the URL as a string. Sep 15 at 8:14
In Drupal 7 you can also use MYSQL query, if you don't want to load all the fields of the file
$fid = 1; //your file ID
$uri = db_select('file_managed', 'f')
->condition('f.fid', $fid, '=')
->fields('f', array('uri'))
->execute()->fetchField();
echo file_create_url($uri);
These are both working for me in Drupal 8:
// top of file
use Drupal\file\Entity\File;
use Drupal\Core\Url;
// load the file object from some file id
$file_object = File::load(123);
// way 1
$file_uri = $file_object->uri->value;
$file_url = file_create_url($file_uri);
// way 2
$file_uri = $file_object->getFileUri();
$file_url = Url::fromUri(file_create_url($file_uri))->toString();
