PHP:getimagesize对上传的文件返回false [英] PHP: getimagesize returns false for uploaded file

问题描述

我知道有很多类似的问题，但是没有一个解决这个特定的问题. 无论如何，我正在尝试获取上传的图像尺寸，然后再将其保存在服务器上.贝娄是我到目前为止尝试过的代码

I know there are many similar questions but none of them addresses this particular problem. Anyway, I'm trying to get the uploaded image dimensions before getting it saved on the server. Bellow is the code that I tried so far

print_r($_FILES);
$temp = getimagesize($_FILES['aaiu_upload_file']['tmp_name']);
print_r($temp);
var_dump($temp);

它输出:

Array
(
    [aaiu_upload_file] => Array
        (
            [name] => Screenshot_4.png
            [type] => image/png
            [tmp_name] => /home/username/tmp/phpN4uRRA
            [error] => 0
            [size] => 19765
        )

)

bool(false)

那么，我在做错什么吗?非常感谢您的帮助.

So, is there something I'm doing wrong? your help is highly appreciated.

我的PHP版本是7.3.1

推荐答案

与php中的getimagesize一样

As in php getimagesize Manual

使用它来获取图像尺寸:

use this to get image dimension :

list($width, $height, $type, $attr) = getimagesize($_FILES['aaiu_upload_file']['tmp_name']);
echo $width.'x'.$height;
