exif_tagname 


php apg

RETRIEVE the EXIF group tag name from its numeric index.





This function returns the header name or FALSE if the $index is not a defined EXIF tag.

(65535)D = (OxFFFF)H tags are possible, however some - currently - are not in use.

In some older versions of PHP the ID must be expressed in hexadecimal notation, otherwise there will be ERROR.



<?php

string|false exif_tagname ( int $index )


where,

$index = The tag ID to retriev the name

?>

  $index   


The tag ID for which a tag name will be looked up.
