1. Set ftp Host,username and password in filesystems.php under the config folder

2.

collect($results)->map(function($result) use($table){

$result["capture_photo_path"]Storage::get(),Storage::size()file_exists()

he will report the error as shown above. I will only return true or false, to him now. If I judge that the file exists and I am deleting the file, I will not do anything if it does not exist. I would like to ask which function is used to judge whether the file on ftp exists, and I check the deletion above the document to determine whether it exists. What should the bosses do
