What are the benefits of using readfile() over imagecreatefromjpeg and imageJpeg functions in PHP for displaying images?

Using readfile() to display images in PHP is more efficient than using imagecreatefromjpeg and imageJpeg functions because readfile() directly outputs the image file to the browser without the need to load it into memory. This can help reduce memory usage and improve performance when dealing with large image files. Additionally, readfile() is simpler to use and requires less code compared to the imagecreatefromjpeg and imageJpeg functions. 

<?php
// Display image using readfile()
$imagePath = 'path/to/image.jpg';
header('Content-Type: image/jpeg');
readfile($imagePath);
exit;
?>
