What are the potential pitfalls of using PNG files to display text on a website and how can PHP be utilized to improve this process?

Using PNG files to display text on a website can lead to larger file sizes, slower loading times, and decreased text quality compared to using HTML and CSS for text rendering. To improve this process, PHP can be utilized to dynamically generate text as images using the GD library, allowing for faster loading times and better quality text rendering. 

<?php
// Create a blank image with specified width and height
$image = imagecreate(200, 50);

// Set the background color to white
$bg_color = imagecolorallocate($image, 255, 255, 255);

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

// Add text to the image
$text = "Hello, World!";
imagettftext($image, 20, 0, 10, 30, $text_color, 'arial.ttf', $text);

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

// Output the image
imagepng($image);

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