我收到以下解析错误:

解析错误:第7行上的H:\ Programs\USBWebserver v8.5\8.5\root\oopforum\func\register.class.php中的语法错误,意外'(',期待','或';')

这与我班上的以下代码行有关:

        private $random_name = rand(1000,9999).rand(1000,9999).rand(1000,9999).rand(1000,9999);
        private $path = 'img/thumb_/'.$random_name. $_FILES['file']['name'];
        private $max_width = 4040;
        private $max_height = 4040;
        private $max_size = 5242880;
        private $temp_dir = $_FILES['file']['tmp_name'];
        private $image_type = $_FILES['file']['type'];
        private $image_size = $_FILES['file']['size'];
        private $image_name = $_FILES['file']['name'];
        private $image_dimensions = getimagesize($temp_dir);
        private $image_width = $image_dimensions[0]; // Image width
        private $image_height = $image_dimensions[1]; // Image height
        private $error …
