文件上传PHP JPG问题

Question

I'm getting confused while working with an file upload HTML form and some PHP to handle the input. In the form i have two file selects for images. When uploading an .png file i can get the file size etc using $_FILES. But when i'm trying to upload an .jpg file, i can't get more then the filename, no size, type, temporary name.

And when uploading two files at once, .png and .jpg, everything works for the .png file but not the .jpg.

What am i missing here? Are there any "restrictions when using $_FILES with .jpg filetypes or something else that i'm not aware of?

Example code:

    if (isset($_FILES['upload1'])) {            // JPG FILE
        $fileName1 = $_FILES['upload1']['name'];
        $fileSize1 = $_FILES['upload1']['size'];
        echo $fileName1;
        echo $fileSize1;
    }
    if (isset($_FILES['upload2'])) {            // PNG FILE
        $fileName2 = $_FILES['upload2']['name'];
        $fileSize2 = $_FILES['upload2']['size'];
        echo $fileName2;
        echo $fileSize2;
    }

outputs something like (without the brackets):

"filename1.jpg" "0" "filename2.png" "12313"

print_r($_FILES) outputs:
Array (
[upload1] => Array (
[name] => volvo1.png
[type] => image/png
[tmp_name] => C:\\wamp\\tmp\\php14AD.tmp
[error] => 0
[size] => 6380 )

[upload2] => Array (
[name] => IMG0379.JPG
[type] => [tmp_name] =>
[error] => 1
[size] => 0 )
)

问题已解决，对于那些可能遇到相同问题的人来说，解决方案就像更改 php.ini 中的 upload_max_filesize 一样简单。

Markus right, change the upload_max_filesize in /etc/php/7.3/apache2/php.ini

; http://php.net/upload-max-filesize
upload_max_filesize = 200M

if still not, maybe install these library

apt-get install -y libpng-dev 
apt-get install -y    libwebp-dev 
apt-get install -y    libjpeg62-turbo-dev 
apt-get install -y    libjpeg-dev 
apt-get install -y    libpng-dev libxpm-dev 
apt-get install -y    libfreetype6-dev
