What are the advantages and disadvantages of using GDLib commands to generate text on an image in PHP?

Using GDLib commands to generate text on an image in PHP allows for dynamic text generation on images, which can be useful for creating personalized graphics or adding labels. However, it can be resource-intensive and may slow down the loading time of the image. Additionally, the text generated using GDLib may not be as high quality or customizable as using a graphic design software. 

// Create a new image
$image = imagecreatefromjpeg('image.jpg');

// Set the font size and color
$font_size = 20;
$font_color = imagecolorallocate($image, 255, 255, 255);

// Add text to the image
$text = "Hello, World!";
imagettftext($image, $font_size, 0, 10, 50, $font_color, 'arial.ttf', $text);

// Output the image
header('Content-Type: image/jpeg');
imagejpeg($image);

// Free up memory
imagedestroy($image);
