在php中将上传封装成类

在使用上传文件时，将上传的代码封装成类，更容易方便。

 

190.php

<?php

require('upload.php');

if($_POST['submit']){

$a = new Upload();

$File = $a -> uploadfile($ARG=array(

'File'=>array(

'name' => $_FILES['fileDoc']['name'],         //原名字

'tmp_name' => $_FILES['fileDoc']['tmp_name']  //新名字

)));

}

echo $File['oldname'];

?>

<form action="<?echo $PHP_SELF?>" method="post" enctype="multipart/form-data">

<input type="file" name="fileDoc">

<br>

<input type="submit" name="submit" value="上传">

</form>
