laravel file upload tmp file

Question

Hello guys when I use file upload and save link in database it save this "/tmp/phpkPhygr|public/allFiles/files/26657d5ff9020d2abefe558796b99584/69adc1e107f7f7d035d7baf04342e1ca.gif" so why "tmp/php..." show in this link or I want to remove this to work this url.

        $files = array();
    if($files = $request->file('files')){
        foreach($files as $file){
            $fileName = md5(rand(100,1000)) . "." . strtolower($file->getClientOriginalExtension());
            $folder='public/allFiles/files/' . md5(rand(100,10));
            $file_url = $folder . "/" . $fileName;
            $file->move($folder, $fileName);
            $files[] = $file_url;
        }
    }
    $filesReq = $files;
    if($filesReq == ' '){
        $filesReq = 'no files';
    }else{
        $filesReq = implode('|', $files);
    }
