Convert Text to Image with PHP GD: A Beginner's Guide

This beginner's guide will teach you how to convert text to images using PHP's GD'll learn how to use GD to generate images from text strings, set font

Here's an example PHP code that converts text to an image using GD library:

 // Set the content type header
header('Content-Type: image/png');

// Create a new image with specified dimensions
$image = imagecreate(400, 200);

// Set the background color
$background_color = imagecolorallocate($image, 255, 255, 255);

// Set the text color
$text_color = imagecolorallocate($image, 0, 0, 0);

// Set the font size and font path
$font_size = 20;
$font_path = 'arial.ttf';

// Write the text to the image
$text = 'Hello, World!';
imagettftext($image, $font_size, 0, 10, 100, $text_color, $font_path, $text);

// Output the image to the browser

// Free up memory

In this code, we first set the content type header to image/png so that the browser knows to expect an image. We then create a new image using the imagecreate function and specify its dimensions.

Next, we set the background color of the image using the imagecolorallocate function and specify the RGB values for the color. We also set the text color using the same function.

We then set the font size and font path using variables, and write the text to the image using the imagettftext function. This function takes the image resource, font size, angle, X and Y coordinates, text color, font path, and text string as parameters.

Finally, we output the image to the browser using the imagepng function and free up memory using the imagedestroy function.
