PHP implementation of multiple file upload classes and usage examples _php tips

This article describes the PHP implementation of the multiple file upload class and usage. Share to everyone for your reference, specific as follows:

1, upFiles.css.php documents

2, the use of methods

uploade.php file:

<?php
//print_r ($_files[' spic '));
Header (' Content-type:text/html;charset=utf-8 ');
if (@$_files[' spic ']) echo "ddddddddd";;
Include (' upFiles.css.php ');
$upfile = new Uploadfiles Array (' filepath ' => './upload ', ' Allowtype ' =>array (' php ', ' bmp ', ' gif ', ' jpg ', ' png '), ' Israndfile ' =>true, ' maxsize ' => ' 1000000 ');
if ($upfile->uploadefile (' spic ')) {
 $arrfile = $upfile->getnewfile ();
 foreach ($arrfile as $v) {
 echo $v, "<br/>";
 }
 echo "Upload success!" ";
} else{
 $err = $upfile->gteerror ();
 if (Is_array ($err)) {
 foreach ($err as $v 1) {
  echo $v 1, ' <br/>
 }
 }} else{
 echo $err;
 }
 Var_dump ($err);
Var_dump ($upfile);
