多文件上传其实就包括了图片及各种文件了,下面介绍的是一款PHP多文件上传类,一共两个文件,upp.php 和 uploadFile.php,upp.php,这是前台所显示的表单文件了,默认的是四个上传文件域,我们可以手动进行修改,另外这个页面嵌套了 uploadFile.php 文件上传类,下面一起来看例子.
php文件上传例子,代码如下:
<?php
header( 'content-type:text/html;charset=utf-8' );
require ( 'uploadFile.php' );
if (isset( $_POST [ 'submit' ])){
$uploads = $_FILES [ 'file' ];
$num_file = count ( $uploads [ 'name' ]);
$up = new UploadFile( $uploads , 'uploads' ,1024);
$num = $up ->upload();
if ( $num == $num_file ){
echo '全部文件上传成功' ;
exit ;
} else {
echo $num , '个文件上传成功<br/>' ;
echo $up ->showErrorInfo();
exit ;
}
}
?>
