exif_tagname

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';$tagg = exif_tagname(0XA003);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:<?phpfor ($id = 1; $id <= 65535; $id++){$dec2hex = dechex($id);$strgx = '0x'. $dec2hex;if(exif_tagname($strgx) != ""){echo $strgx . ' ( ' . exif_tagname($strgx) . ' )<br />';}}?>
