PHP - changing metadata of a JPEG

Or other image file. Can this be done in a (fairly) simple way using PHP?

I'm coding a website that will allow users to upload photos, but I know JPEGs are notorious for their metadata and ideally I'd like to strip all images uploaded of metadata, either by removal or replacement with junk text.

If you're just looking to strip most of the exif data quickly and easily without using a library to specifically write it, you can 'resave' the image using gd:

$file = 'myjpg.jpg';
$im = imagecreatefromjpeg($file);
imagejpeg($im, 'myjpg2.jpg');

Maybe not the best/prettiest solution, but it accomplishes what you want without adding additional libraries.
