file_get_mimetype

6 file.inc file_get_mimetype($filename, $mapping = NULL)
7 file.inc file_get_mimetype($uri, $mapping = NULL)

Determine an Internet Media Type, or MIME type from a filename.

Parameters

$uri: A string containing the URI, path, or filename.

$mapping: An optional map of extensions to their mimetypes, in the form:

  • 'mimetypes': a list of mimetypes, keyed by an identifier,
  • 'extensions': the mapping itself, an associative array in which the key is the extension (lowercase) and the value is the mimetype identifier. If $mapping is NULL file_mimetype_mapping() is called.

Return value

The internet media type registered for the extension or application/octet-stream for unknown extensions.
