How to obtain picture metadata using perl, php

How do I obtain the metadata for a png or jpg image? I have a few thousand images that get processed by a perl script. One of the things that I need to be able to get from each image is the metadata for them.

The most important information is the date listed in bold. I would like to have a script I can run that will grab the date info from each of the pictures that I process. It would be ideal if it is in perl, but php would work too. this is running on a Linux system. Any help would be appreciated. Thank you

Here is an example of one of the images: alt text

Here is the metadata for this image:

You can use ImageMagick, it's good application that was used in Typo3 to retrieve image's MetaData. when you want to execute it, you can use the exec() or system() functions
