This PHP code takes an existing image file, pig.jpg, and adds text to it. The text "Happy Valentine" is added in red using the Verdana font at a size of 10 pixels and positioned at coordinates 25, 110 pixels on the image. The modified image is then output as a PNG file to allow it to be displayed in the browser with the text overlayed on the original image.

1. Add text on Image -Image processing in PHP
<?php
// Import the image to use
$TheImage = imagecreatefromjpeg("pig.jpg");
//Choose the Color of the text...(255,0,0 is red)
$ColorText = imagecolorallocate($TheImage, 255, 0, 0);
// printing the text:.
imagettftext($TheImage, 10, 60, 25, 110, $ColorText, "Verdana", "Happy Valentine");
// Let the browser know that it is an png image..
header("Content-Type: image/png");
// show the image in png format...(png format is clearer
imagepng ($TheImage);
?>
