php图片上传报错error=3

upload:

<?php
/**

• Created by PhpStorm.
• User: rosen
• Date: 15-11-5
• Time: 下午8:43 */ print_r($_FILES['file']);

?>

为什么程序运行结果报错Array ( [name] => 2015-10-19 18:47:42屏幕截图.png [type] => [tmp_name] => [error] => 3 [size] => 0 )

php上传出现错误，代号为3，表示是文件只有部分被上传 .

看文档 http://php.net/manual/en/features.file-upload.errors.php
