2. usage

Uploade. php file:

<? Php // print_r ($ _ FILES ['spic ']); header ('content-Type: text/html; charset = utf-8 '); // if (@ $ _ FILES ['spic ']) echo "ddddddddddd" implements include('upfiles.css. php '); $ upfile = new UploadFiles (array ('filepath' => '. /upload ', 'allowtype' => array ('php', 'bmp', 'GIF', 'jpg ', 'PNG'), 'israndfile' => true, 'maxsize' => '20140901'); if ($ upfile-> uploadeFile ('spic') {$ arrfile = $ upfile-> getnewFile (); foreach ($ arrfile as $ v) {echo $ v ,"
