Laravel 5 |文件上传 - 如果文件存在，则在文件名中添加数字

Question

我在上传文件时遇到问题。现在我有这样的东西（控制器的一部分）：

if($request->has('photos')) {
            foreach ($request->photos as $photo) {
                $filename = $photo->getClientOriginalName();
                $tmp_name = $filename;

                if ($pos = strrpos($filename, '.')) {
                    $name = substr($filename, 0, $pos);
                    $ext = substr($filename, $pos);
                    
                } else {
                    $name = $filename;
                }

                $uniq_no = 0;
                while (file_exists($filename)) {
                    $tmp_name = $name .'_'. $uniq_no . $ext;
                    $uniq_no++;
                    
                }
                $photo->storeAs('public/photos/',$tmp_name);
                Photo::create([
                    'page_id' => $page->id,
                    'filename' => $tmp_name
                ]);
            }
        }

但保存到数据库中不添加唯一编号：filename_0、filename_1 等。它只是保存 $tmp_name 的值。

我做错了什么？

我做了这样的事情：

if($request->has('photos')) {
            foreach ($request->photos as $photo) {
                $file = $photo->getClientOriginalName();
                $filename = pathinfo($file, PATHINFO_FILENAME).'_'.Str::random(6);
                $extension = pathinfo($file, PATHINFO_EXTENSION);
                $fullfilename = $filename .'.'. $extension;
                $photo->storeAs('public/photos/',$fullfilename);
                Photo::create([
                    'page_id' => $page->id,
                    'filename' => $fullfilename
                ]);
            }
        }
