Method Details

__construct() public method

Constructor
public __construct ( $config = [] ) : void
return void

_file_mime_type() protected method

Detects the (actual) MIME type of the uploaded file, if possible. The input array is expected to be $_FILES[$field]
protected _file_mime_type ( array $file ) : void
$file array
return void

_prep_filename() protected method

Prevents possible script execution from Apache's handling of files' multiple extensions.
See link: http://httpd.apache.org/docs/1.3/mod/mod_mime.html#multipleext
protected _prep_filename ( string $filename ) : string
$filename string
return string

return string

get_extension() public method

Extract the file extension
public get_extension ( string $filename ) : string
$filename string
return string

initialize() public method

Initialize preferences
