Text and watermark Image Integration in php

I have to codes below that works seperately.
The first was used to upload image to a server and database via pdo connection.
The second was used to watermark a stationary image.

My problem is that i want to combine the two codes so as to text watermark an image during upload to Server without the aids
of globle variable.
I have been working on this but cannot get it to work. can someone help me to integrate this. Thanks

Code:

<?php
include('pdo.php');





        if (!isset($_FILES['image']['tmp_name'])) {
        echo "";
        }else{
        $file=$_FILES['image']['tmp_name'];
        $image= addslashes(file_get_contents($_FILES['image']['tmp_name']));
        $image_name= addslashes($_FILES['image']['name']);
        $image_size= getimagesize($_FILES['image']['tmp_name']);

       
                if ($image_size==FALSE) {
               
                        echo "That's not an image!";
                       
                }else{
                       
                        move_uploaded_file($_FILES["image"]["tmp_name"],"postphoto/" . $_FILES["image"]["name"]);
                       
                        $location="postphoto/" . $_FILES["image"]["name"];
                        $from=$_POST['from'];
                        $time=time();
                        $photos='photos';




$statement = $db->prepare('INSERT INTO text_watermark (photo,from_send) values(:photo,:from_send)');

if(!$statement->execute(array(

':photo' => $photos,
':from_send' => $from))){
                                echo 'There is problem';
                               
                               
                        }
                        else{
                       
                        header("location: lol.php");
                        exit();
                        }
                        }
        }


?>

<?php
      //Set the Content Type
      header('Content-type: image/jpeg');

      // Create Image From Existing File
      $jpg_image = imagecreatefromjpeg('sunset.jpg');

      // Allocate A Color For The Text
      $white = imagecolorallocate($jpg_image, 255, 255, 255);

      // Set Path to Font File
      $font_path = 'font.TTF';

      // Set Text to Be Printed On Image
      $text = "This is a sunset!";

      // Print Text On Image
      imagettftext($jpg_image, 25, 0, 75, 300, $white, $font_path, $text);

      // Send Image to Browser
      imagejpeg($jpg_image);

      // Clear Memory
