Question

我正在尝试使用html输入标记上传更大尺寸的图像，如4608X3500像素。但无法获得文件大小。

我正在使用此代码获取文件详细信息：

    $userfile_name = $_FILES['image']['name'];
$userfile_tmp = $_FILES['image']['tmp_name'];
$userfile_size = $_FILES['image']['size'];
$userfile_type = $_FILES['image']['type'];
$filename = basename($_FILES['image']['name']);

在此，我没有得到类型值和大小值显示为0.

Answer 1

可能文件太大了。什么

var_dump($_FILES['image']['error'])

显示？如果它不为零，则发生错误。代码在此处定义：http://php.net/manual/en/features.file-upload.errors.php

Answer 2

更改php.ini中的upload_max_filesize

Answer 3

C：\瓦帕\ BIN \ PHP中\ php5.2.6

在这个搜索php.ini文件中，你需要设置upload_max_filesize ...

Answer 4

有时我们上传的文件少于2 MB。它正常上传，因为在php.ini默认情况下upload_max_filesize有2M，这意味着2 MB。在另一个手文件大小超过2 MB需要在php.ini upload_max_filesize中进行更改。您也可以使用
