Req #69854 [Asn->Opn]: Facilitate reading and parsing of IPTC/XMP metadata

I've downloaded the image and this script: <?php $data = array_intersect_key( exif_read_data('./69854.jpg'), ['Copyright' => null, 'Make' => null, 'Model' => null] ); var_dump($data); produces: array(3) { ["Make"]=> string(1) "☺" ["Model"]=> NULL ["Copyright"]=> string(10) "llesvds.fr" } Apparently, this is nonsense, but Adobe Lightroom concentrates not on classic EXIF, but rather on IPTC metadata in XMP format[1]. IPTC metadata are not subject of exif_read_data(), but rather of iptcparse(). Using the example from the iptcparse() man page[2] yields somewhat better results, but still not what is desired. I believe, however, that this is not a bug in iptcparse(), because the documentation states: | Parse a binary IPTC block into single tags. XMP format is, however, not binary, but an application of XML. Therefore I'm switching this ticket to feature request. You may consider to look for a PHP library which can read and parse IPTC/XMP metadata.
