如何在PHP的$ _FILE数组中查看错误消息

Question

我正在使用多种文件上传功能，在将文件数组打印为时出现错误：

  print_r($_FILE);

获取错误为：

Array
(
   [name] => _agiewniki_Forrest_in_Autumn.jpg
   [type] =>
   [tmp_name] =>
   [error] => 1
   [size] => 0
)

我没有看到错误说明，仅此错误

[error] => 1

Answer 1

您可以使用此数组显示文件上传错误消息 ：

$error_messages = array(
    UPLOAD_ERR_OK         => 'There is no error, the file uploaded with success',
    UPLOAD_ERR_INI_SIZE   => 'The uploaded file exceeds the upload_max_filesize directive in php.ini',
    UPLOAD_ERR_FORM_SIZE  => 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form',
    UPLOAD_ERR_PARTIAL    => 'The uploaded file was only partially uploaded',
    UPLOAD_ERR_NO_FILE    => 'No file was uploaded',
    UPLOAD_ERR_NO_TMP_DIR => 'Missing a temporary folder',
    UPLOAD_ERR_CANT_WRITE => 'Failed to write file to disk',
    UPLOAD_ERR_EXTENSION  => 'A PHP extension stopped the file upload',
);

// prints "The uploaded file exceeds the upload_max_filesize directive in php.ini"
echo $error_messages[$_FILES['error']];

Answer 2

http://www.php.net/manual/zh/features.file-upload.errors.php

UPLOAD_ERR_INI_SIZE值：1； 上传的文件超出了php.ini中的upload_max_filesize指令。

希望对大家有帮助

Answer 3

在这里您可以通过错误代码找到说明

您的情况是： The uploaded file exceeds the upload_max_filesize directive in php.ini.

Answer 4

基于$_FILES['userfile']['error']值，您可以在ref文档中打印相应的错误消息。

将所有错误消息添加到具有相应错误键值的某个数组中。 根据上传过程中从$_FILE接收到的错误键值，并显示相应的错误消息[在下面添加链接]。

错误消息解释：

错误值：1； 上传的文件超出了php.ini中的upload_max_filesize指令。
