How can one efficiently insert text into an image using PHP functions?

To efficiently insert text into an image using PHP functions, you can use the GD library which provides functions for image manipulation. You can create a new image with the text overlayed on top of the original image by using functions like `imagecreatefromjpeg`, `imagecopy`, and `imagettftext`. 

// Load the original image
$originalImage = imagecreatefromjpeg('original.jpg');

// Set the text color and font
$textColor = imagecolorallocate($originalImage, 255, 255, 255);
$font = 'arial.ttf';

// Insert text into the image
imagettftext($originalImage, 20, 0, 10, 50, $textColor, $font, 'Sample Text');

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

// Free up memory
imagedestroy($originalImage);
