How can PHP be used to integrate Exif data into webp, png, and jpg images on the fly, considering the restrictions of existing PHP functions like iptcembed?

To integrate Exif data into webp, png, and jpg images on the fly using PHP, we can use the `exif_read_data` function to extract the Exif data from the original image and then use the `iptcembed` function to embed the Exif data into the new image. However, `iptcembed` function only works with JPEG images, so for PNG and WebP images, we need to find an alternative method to embed the Exif data.

// Read Exif data from the original image
$exif_data = exif_read_data('original_image.jpg');

// Embed Exif data into the new image
$new_image = 'new_image.jpg';
$iptc_data = iptcembed(serialize($exif_data), $new_image);

// Save the new image with embedded Exif data
file_put_contents($new_image, $iptc_data);
