MIME

MIME type and file extension utilities for PHP. Powered by finfo and the Apache-provided public domain mime.types map of media types to unique file extension(s).

Examples

To get started, use the namespace wherever you want to use this library.

use Karwana\Mime;

For uploaded files

First we get the canonical extension and use it for the permanent file name. The original file name is used before falling back to running finfo if the file has no extension or if the extension is unlisted.

$extension = Mime::guessExtension($_FILES['my_file']['tmp_name'], $_FILES['my_file']['name']);

move_uploaded_file($_FILES['my_file']['tmp_name'], 'uploads/' . Uuid::v4() . '.' . $extension);

Later on, if we want to serve the file to the client, we can return the appropriate MIME type.

header('Content-Type: ' . Mime::guessType($my_file));
header('Content-Length: ' . filesize($my_file));
readfile($my_file);

Add an extension to an extensionless file

You might want to do this as part of a batch job.

$my_file = 'path/to/extensionless_file';

rename($my_file, $my_file . '.' . Mime::guessExtension($my_file));

Development
