不在服务器中上传图片

<?php
function uploadImage($file,$dir,$thumb_dimension = null) // 1920 x 768
{
    $path = public_path() . '/uploads' . $dir;

    if (!File::exists($path)) {
        File::makeDirectory($path, 0777, true, true);
    }

    $file_name = ucfirst($dir) . '-' . date('Ymdhis') . rand(0, 999) . " . " . $file->getClientOriginalExtension();

    $success = $file->move($path, $file_name);

    if ($success){
        $file_path = $path.'/'.$file_name;

        if ($thumb_dimension){

            list($width,$height) = explode('x',$thumb_dimension);

            Image::make($file_path)->resize(300,200,function ($constraint){
                $constraint->aspectRatio();
            })->save($path.'/Thumb-'.$file_name);
        }

        return $file_name;
    }else{
        return null;
    }
}
