HTTP_Upload简介分享

Pear的HTTP_Upload类库提供了一个封装好的html表单文件上传处理程序，使用Pear的error系统。

特点
能一次处理多个文件的上传
容易校验文件的上传状态，限制不期望的文件上传
多语种的报错提示信息（还没有中文，不过可以扩展)
单个文件上传的例子
index.htm

PLAIN TEXT
CODE:
<form action=”./files.php” enctype=”multipart/form-data”>
File 1: <input type=”file” name=”userfile”><br>
<input type=”submit” name=”submit” value=”Upload!”>
</form>
files.php

PLAIN TEXT
PHP:
<?php
require ‘HTTP/Upload.php’;
$upload = new HTTP_Upload(‘es’);
// Language for error messages
$file = $upload->getFiles(‘userfile’);
// return a file object or error
if (PEAR::isError($file)) {
    die ($file->getMessage());
}
// Check if the file is a valid upload
if ($file->isValid()) {    // this method will return the name of the file you moved,   
    // useful for example to save the name in a database   
    $file_name = $file->moveTo(‘./uploads_dir/’);
    if (PEAR::isError($file_name)) { 
        die ($file_name->getMessage());
    }
}
?>
