Create a PHP file and save the below code in that file.
Add an image to the same folder or directory with the file name image.jpg.
Put a TTF font file too in the same directory.
You are all set.

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

  
  $image = imagecreatefromjpeg('image.jpg');

  
  $textcolor = imagecolorallocate($image, 255, 255, 255);

  
  $font_file = 'myfont.ttf';

  
  $custom_text = "Watermark Text";

  
  imagettftext($image, 225, 0, 3450, 3000, $textcolor, $font_file, $custom_text);

 
  imagejpeg($image);

 
  imagedestroy($image); // for clearing memory
?>
 $image = imagecreatefromjpeg('image.jpg');

This creates an Image from an existing image file i.e, image.jpg

I used this image as image.jpg

Watermark

 $textcolor = imagecolorallocate($image, 255, 255, 255);

This is for setting up our text color. I have used RGB color and the above value is for white text color. You can use any color.

 $font_file = 'myfont.ttf';

Thereafter, This is the font location.

I have used This font . You can download it myfont

[ This font file can be used for movie, poster, banner but you are strictly prohibited to use it on webpage, web template, app ]

After downloading this zip file. Extract the font file to your PHP file directory.

 $custom_text = "Watermark Text";

Here we can configure our text, displayed on the image as Watermark.

 imagettftext($image, 225, 0, 3450, 3000, $textcolor, $font_file, $custom_text);

So, this function is for setting up the position of out text and all the other things like, on which image we gonna put our text. Moreover, we can put the text color variable, font file path variable and our custom text variable here.

imagejpeg($image);

This is for sending the image to the browser.
Finally, the last function clears the memory after sending the final watermarked image to the browser.

The final output will look like this
