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 ; } } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" > <html xmlns= "http://www.111cn.net/ 1999/xhtml" > <head> <meta http-equiv= "Content-Type" content= "text/html; charset=utf-8" /> <title>无标题文档</title> </head> <body> <form action= "uup.php" method= "post" enctype= "multipart/form-data" > <p><input name= "file[]" type= "file" /></p> <p><input name= "file[]" type= "file" /></p> <p><input name= "file[]" type= "file" /></p> <p><input name= "file[]" type= "file" /></p> <input name= "submit" type= "submit" /> </form> </body> </html>PHP文件上传类代码,代码如下:
<?php /*------------*/ class UploadFile { var $user_post_file = array (); var $save_file_path = '' ; var $max_file_size = '' ; var $allow_type = array ( 'gif' , 'jpg' , 'png' , 'zip' , 'rar' , 'txt' , 'doc' , 'pdf' ); var $final_file_path = '' ; var $save_info = array (); var $error_info = array (); /** *构造函数，用于初始化信息。 * *@param Array $file *@param String $path *@param Integer $size *@param Array $type */ function __construct( $file , $path , $size = 2097152, $type = '' ) { $this ->user_post_file = $file ; $this ->save_file_path = $path ; $this ->max_file_size = $size ; if (! $type = '' ){ $this ->allow_type[] = $type ; } } /** * * *@access public *@return int */ function upload() { for ( $i =0; $i < count ( $this ->user_post_file[ 'name' ]); $i ++) { if ( $this ->user_post_file[ 'error' ][ $i ] == 0){ //上传文件状态正常 //获取当前文件名，临时文件名，大小，类型，扩展名 $name = $this ->user_post_file[ 'name' ][ $i ]; $tmp_name = $this ->user_post_file[ 'tmp_name' ][ $i ]; $size = $this ->user_post_file[ 'size' ][ $i ]; $type = $this ->user_post_file[ 'type' ][ $i ]; $ext_name = $this ->getExtName( $name ); //文件大小 if (! $this ->checkSize( $size )){ $this ->error_info[] = '您上传的文件:' . $name .
