How can PHP be used to update an image file on a server with the current date and time information for display on a webpage?

To update an image file on a server with the current date and time information for display on a webpage, you can use PHP to dynamically generate the image file with the current date and time as text overlay. This can be achieved by using PHP's image processing functions to create a new image with the date and time text overlay on top of the original image. 

<?php
// Set the path to the original image file
$original_image = 'path/to/original/image.jpg';

// Create a new image from the original image
$image = imagecreatefromjpeg($original_image);

// Set the font size and color for the date and time text
$font_size = 20;
$text_color = imagecolorallocate($image, 255, 255, 255);

// Get the current date and time
$date_time = date('Y-m-d H:i:s');

// Add the date and time text overlay to the image
imagettftext($image, $font_size, 0, 10, 20, $text_color, 'path/to/font.ttf', $date_time);

// Output the image with the date and time text overlay
header('Content-Type: image/jpeg');
imagejpeg($image);

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