php简单文件图片批量上传程序代码_php教程

批量上传方法也很简单我们只要在给form时加个name=\"pictures[]\" 数组,然后再利用foreach ($_FILES[\"pictures\"][\"error\"] as $key => $error)对数组循环判断,再利用move_uploaded_file($tmp_name, $uploadfile); 实现文件上传就可以了.

html实例代码如下:

<html>

<head><title>upload picture more once</title></head>

<body>

<form action="" method="post" enctype="multipart/form-data">

<p>Pictures:<br />

<input type="file" name="pictures[]" /><br />

<input type="file" name="pictures[]" /><br />

<input type="file" name="pictures[]" /><br />

<input type="submit" name="upload" value="Send" />

</p>

</form>

</body>

</html>

php处理实例代码如下:

<?php

if($_POST['upload']=='Send'){

     $dest_folder    =  "picture/";

if(!file_exists($dest_folder)){

         mkdir($dest_folder);

}

foreach ($_FILES["pictures"]["error"] as $key => $error) {

      if ($error == UPLOAD_ERR_OK) {

         $tmp_name = $_FILES["pictures"]["tmp_name"][$key];

          $name     = $_FILES["pictures"]["name"][$key];

       $uploadfile = $dest_folder.$name;

          move_uploaded_file($tmp_name, $uploadfile);

      }

}

}

?>

方法相当简单我们只是把单文件上传改成了多文件上传,其它只改了二个地方一个是表单名改成php数组形式一种是上传文件地方利用foreach来对数组遍历了.
