Learning how to extract picture metadata through perl and php is a valuable skill to have

Is there a way to access the metadata of png or jpg images in bulk processing? I have a large number of images that need to be processed by a Perl script, and one of the requirements is extracting metadata from each image.

The crucial information needed is the date, which should be extracted and saved automatically. A script that can extract and organize this data would be ideal, preferably in Perl but PHP could work as well. The system being used is Linux. Any assistance on this matter would be greatly appreciated. Thank you!

An example of an image:

Metadata for the image:

Sep 30, 2010

Filename: EA_A02_N_1-4_5mM_Xgal_7d_B.cropped.resized.grey.png

Camera: Canon

Model: Canon EOS DIGITAL REBEL XSi

ISO: 200

Exposure: 1/50 sec

Aperture: 2.8

Focal Length: 60mm

One great tool you can utilize is ImageMagick. It was previously employed in Typo3 for accessing image metadata. To run it, you have the option of using either the exec() or system() functions.
