ถ้าจะ resize image ผมต้องใส่อะไรตรงไหนครับ พอดีเอา code คนอื่นมาแก้ครับ

 mkdir("uploads/$userid");
        $uploadFolder = "uploads/$userid/";

        

        foreach ($_FILES['imageFile']['tmp_name'] as $key => $image) {
            $imageTmpName = $_FILES['imageFile']['tmp_name'][$key];
            $imageName = $_FILES['imageFile']['name'][$key];
        

            $sql = "SELECT * FROM images where imgName = '$imageName' ";
            $query = mysqli_query($con, $sql);
            $ck = mysqli_num_rows($query);
            if ($ck <= 0) {
                $result = move_uploaded_file( $imageTmpName  , $uploadFolder.$img);

                // save to database
                $sql = "INSERT INTO images(userid,imgName,roomtype,jobtype,list,statusjob) VALUES ('$userid','$imageName','-','-','-','9')";
                $query = mysqli_query($con, $sql) or die("Error in query: $sql " . mysqli_error());
