PHP：在上传时在文件名末尾添加数字（计数1）？ [关闭]

Question

i have an image upload script and i have the file name set to save as 'thumb_pic.jpg' on upload. But i want users to be able to upload a maximum of 8 different photos, with the same name but i just want to add 1-8 at the end of each file name like so:

'thumb_pic1.jpg', 'thumb_pic2.jpg' etc.

Here's the snippet of my code which is where the file name is set. Can anyone tell me what i'd need to add to do what i'm trying to do? Thanks.

 $filename = $_POST['value'] ? $_POST['value'] :
            $folder . 'thumb_pic.jpg'; 

Answer 1

$filename = .... $folder . 'thumb_pic' . $i . '.jpg';
                                      ^^^^^^^^

where $i is your 1-8 value. Generating it is up to you, since you don't specify how your file upload form or server-side handling scripts are constructed.
