In association with exif_read_data:

<?php

# The tagnames can vary in different cameras

$imgdir = "/path_to_img/";
$img_file = "image_file.jpg";

echo
$img_file . "&nbsp;&nbsp;&nbsp;<sub>TEST</sub>
<br />"
;
echo
'<img src="' . $imgdir . $img_file . '" alt="'
 
. $img_file . '" title="' . $img_file . '" width="400" /><br /><br />';

$xf_data = exif_read_data($imgdir . $img_file);

$tagg = exif_tagname(0X10F);
echo
'<br>' . $tagg ' >>> ' . $xf_data[$tagg];
$tagg = exif_tagname(0X110);
echo
'<br>' . $tagg ' >>> ' . $xf_data[$tagg];
$tagg = exif_tagname(0X132);
echo
'<br>' . $tagg ' >>> ' . $xf_data[$tagg];
$tagg = exif_tagname(0XA002);
echo
'<br>' . $tagg ' >>> ' . $xf_data[$tagg] . 'px';

Theoretically, 65,535 tags are possible. Although not all are used, yet. The code below lists these tags:

<?php

for ($id = 1; $id <= 65535; $id++)
{
$dec2hex = dechex($id);

$strgx = '0x'. $dec2hex;

if(
exif_tagname($strgx) != "")
{
echo
$strgx . ' ( ' . exif_tagname($strgx) . ' )<br />';
}
}

?>

Usage: exif_tagname(0x5001)

A list of all supported index numbers is in the exif.c: tag_table_IFD

http://cvs.php.net/viewvc.cgi/php-src/ext/exif/exif.c?view=markup

As you can see, it doesn't support them all!
