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

Edit report at https://bugs.php.net/bug.php?id=69854&edit=1 ID: 69854 Updated by: cmb@php.net Reported by: gillesvds at adok dot info -Summary: exif_read_data() does not conform with industry standards +Summary: Facilitate reading and parsing of IPTC/XMP metadata -Status: Assigned +Status: Open -Type: Bug +Type: Feature/Change Request -Package: EXIF related +Package: *Graphics related Operating System: Windows or Linux PHP Version: 5.4.42 Assigned To: cmb Block user comment: N Private report: N New Comment: Thanks. 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.
