Problem with updating and unlinking old image PHP - php

Question

So problem is that I created 2 methods to set files and check the image if there is an image in tmp, it should delete the old image before moving a new one. But when I upload an image, unlink gives an error like this unlink(\Users\Murat\Desktop\xampp\htdocs\new\usersimages\42\1593769114256123131.jpg): No such file or directory in this number belongs to what I uploaded not the old image.
It moves a new image to the folder and try to delete new image but not delete old. this is the main problem. Probably I do a mistake but can't find where. The codes are below.
public function set_file($file){
$this->image = basename($file['name']);
$this->tmp_path = $file['tmp_name'];
$this->type = $file['type'];
$this->size = $file['size'];
$this->image = preg_replace('#[^a-z.0-9]#i', '', $this->image);
$kaboom = explode(".", $this->image); // Split file name into an array using the dot
$fileExt = end($kaboom); // Now target the last array element to get the file extension
$this->image = time().rand().".".$fileExt;
}
public function checkPhoto($user_id){
global $database;
if(!empty($this->tmp_path)) {
$path = $this->upload_directory.$user_id.DS.$this->image;
unlink($path);
move_uploaded_file($this->tmp_path,
$path);
// unlink("album_uploads/$this->image");
} elseif (empty($this->tmp_path)) {
$sql = "SELECT * FROM users WHERE user_id = :user_id ";
$query =$database->query($sql, [':user_id'=>$user_id]);
$row = $query->fetch();
$this->image = $row['image'];
$this->type = $row['type'];
$this->size = $row['size'];
} else {
$this->errors[] = "Unexpected error please try again after refresh the page!";
}
}

Answer 1

So I added this part in the checkphoto method and it works now. if I did a mistake please let me know who can have more knowledge.
public function checkPhoto($user_id){
global $database;
$sql = "SELECT * FROM users WHERE user_id = :user_id ";
$query =$database->query($sql, [':user_id'=>$user_id]);
$row = $query->fetch();
$path = $this->upload_directory.$user_id.DS;
if(!empty($this->tmp_path)) {
$this->image = $row['image'];
if (file_exists($this->image)) {
unlink($path.$this->image);
}
// unlink("album_uploads/$this->image");
} elseif (empty($this->tmp_path)) {
$this->image = $row['image'];
$this->type = $row['type'];
$this->size = $row['size'];
} else {
$this->errors[] = "Unexpected error please try again after refresh the page!";
}
}
