getName (). '; // Return file complication name Echo' file type: '. Upfos -> getExt (). '; // Return to file size Echo' file size: '. $ upfos -> getSize ().'; / * getSize (Format) Format: Return to file size Unit value. The default is B. B is byte m for MB: getSize ('b'); * // Randomly generated file name Echo 'random file:'. $ Upfos -> newname (). '; / * Suggestions Randomly generated file names to avoid uploading reputation files. For example: $ upfos -> Upload ($ upfos -> newname ()); * / / Upload file $ upfos -> upload (); / * UPLOAD (filename) FileName: Generate this file name after uploading to the server. The default is the original file name. * / / Generate thumbnails $ upfos -> thumb (); / * thumb ([Key, Width, Height]) Key: Generates a keyword for the thumbnail. The default is "SM_".
