I'm trying to do a class for Code Igniter to get all the Exif Data from uploaded images. First of all I'm trying to understand how ExifTools works... I have instaled the lib on my mac and testing with terminal.app, works fine. But now, I need to execute the lib using "exec" from php? How can I do for get the data into array? How can I change the data for differents lenguages? I'm really newbie in Perl libraries, hope somebody can help me. Thanks!
