How can text be output as an image in PHP?

To output text as an image in PHP, you can use the GD library which provides functions for creating and manipulating images. You can create a new image, set the text color, font size, and font type, and then use the `imagettftext()` function to write the text onto the image. Finally, you can output the image using the appropriate header and `imagepng()` function. 

<?php
// Create a blank image
$image = imagecreate(200, 50);

// Set the text color
$textColor = imagecolorallocate($image, 255, 255, 255);

// Set the font size and font file
$fontSize = 20;
$fontFile = 'arial.ttf'; // Path to your font file

// Write text onto the image
imagettftext($image, $fontSize, 0, 10, 30, $textColor, $fontFile, 'Hello, World!');

// Output the image
header('Content-Type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);
?>
