Sort by date picture taken

[brandoncall]

Hi,

I am displaying a bunch of pictures on my website and I would like to
sort them by a Date Picture Taken key. I have looked into exif data
and I wrote a little code that just prints all the keys and their
contents.
Code:
$file = "MyPicture.jpg";
$exif = read_exif_data ("$file");
while(list($k,$v)=each($exif))
{
echo "$k: $v<br>\n";
}

For date picture taken, All I get is:

FileName: MyPicture.jpg
FileDateTime: 1180959961
....
ExifVersion: 1220
DateTimeOriginal:
DateTimeDigitized:
CompressedBitsPerPixel: 892484151/3289658
....

nothing as you can see. Here is the info from phpinfo about my exif
setup:
exif
EXIF Support enabled
EXIF Version 1.4 $Id: exif.c,v 1.173.2.5 2006/04/10 18:23:24 helly
Exp $
Supported EXIF Version 0220
Supported filetypes JPEG,TIFF

When I download the jpg, I can view/sort by the date picture taken
using Windows Explorer.

Does anyone know why I am not seeing the DateTimeOriginal information?

If anyone knows a better way to sort by Date Picture Taken On, I'd
love to hear it. Windows can do it so it must be in there somewhere.

Not sure, explorer may be falling back to a different value in the
absence of DateTimeOriginal. Btw, this tool can set the
DateTimeOriginal field: http://www.exifpro.com/Help/ToolDateTime.htm
