How To Write Text on Cake Image Using PHP?

Let’s create a PHP file as “text-on-image.php” and also you need a cake image where you have to write your text.

Open file and write this complete code into it,


// Path to your existing image
$imagePath = 'cake-image.jpg'; // Replace this with your image path

// Get the image information to determine its type
$image_info = getimagesize($imagePath);

// Load the existing image based on its type
if ($image_info['mime'] == 'image/jpeg') {
    $image = imagecreatefromjpeg($imagePath);
} elseif ($image_info['mime'] == 'image/png') {
    $image = imagecreatefrompng($imagePath);
} else {
    die('Unsupported image type.'); // Stop the script if the image type is unsupported

// Set the font color (black in this example)
$textColor = imagecolorallocate($image, 255, 255, 255);

// Set the text to be written
$text = "Happy Birthday \nSanjay Kumar"; // Your text here

// Set the font path and size
$font = 'Rubik_Bubbles/RubikBubbles-Regular.ttf'; // Replace with your font file path
$fontSize = 20;

// Set the position to place the text (coordinates)
$textX = 250;
$textY = 200;

$angle = -20; // Change this value to set the rotation angle

// Attempt to write the text onto the image
if (!file_exists($font)) {
    die('Font file not found.');

// Write the text with different shades and positions to simulate 3D effect
imagettftext($image, $fontSize, $angle, $textX, $textY, $textColor, $font, $text);

// Check if the font file exists
if (!file_exists($font)) {
    die('Font file not found.');

// Check if imagettftext function is available
if (!function_exists('imagettftext')) {
    die('GD library does not support FreeType fonts.');

// Set the content type header to display the modified image
header('Content-type: '.$image_info['mime']);

// Output the modified image
if ($image_info['mime'] == 'image/jpeg') {
} elseif ($image_info['mime'] == 'image/png') {

// Free up memory

Code Explanation

Here’s what each part of the code does:

  • Error Reporting: Enables reporting of all PHP errors for debugging purposes.
  • Image Path and Type Detection: Defines the path to the existing image and retrieves its MIME type using getimagesize().
  • Image Creation: Loads the existing image using imagecreatefromjpeg() or imagecreatefrompng() based on its MIME type.
  • Text and Font Setup: Defines the text, font file path, font size, text color, text position, and rotation angle.
  • Text Writing: Uses imagettftext() to write the text onto the image with the specified settings. It simulates a 3D effect by drawing text multiple times with slight variations in position and color.
  • Error Checking: Checks if the font file exists and if the imagettftext() function is available in the GD library.
  • Image Output: Sets the content type header based on the image MIME type and outputs the modified image using imagejpeg() or imagepng().
  • Memory Cleanup: Frees up memory by destroying the image resource using imagedestroy().
