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

data() public method

Returns an associative array containing all of the information related to the upload, allowing the developer easy access in one array.

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
