arEmbeddedMetadataParser will extract contextual metadata stored in the file, including description, title, etc. Here's what it extracts: From EXIF tags:
ImageDescription (description/caption) Artist (creator/photographer) Copyright (rights information) Software (editing software used) DateTimeOriginal (when photo was taken) Make/Model (camera info) All technical camera settings (ISO, aperture, shutter speed, etc.) GPS coordinates
From IPTC tags:
Headline (title/headline) Caption/Abstract (description) By-line (creator/author) Keywords (subject terms) Copyright Notice City, Province/State, Country (location info) Credit, Source
From XMP tags:
dc:Title (Dublin Core title) dc:Description (Dublin Core description) dc:Creator (Dublin Core creator) dc:Subject (keywords/subjects) dc:Rights (rights/copyright) xmp:CreateDate, ModifyDate xmp:CreatorTool (software used)
How It Works: arEmbeddedMetadataParser::normalize() function: php$n["title"] = self::firstNonEmpty([ self::collapseLangAlt($m["XMP-dc:Title"] ?? null), // Checks XMP first $m["Title"] ?? null, // Then IPTC ]);
$n["description"] = self::firstNonEmpty([ self::collapseLangAlt($m["XMP-dc:Description"] ?? null), // XMP first $m["ImageDescription"] ?? null, // Then EXIF $m["Description"] ?? null, // Then IPTC ]); The helper uses exiftool with the -j flag, which extracts ALL embedded metadata from the file in one pass. It then normalizes the most important fields into the _norm array for easy access. In the code: When the code call: php$meta = arEmbeddedMetadataParser::extract($filePath); $norm = $meta['_norm'] ?? [];
You get normalized access to: $norm['title'] - from XMP, IPTC, or EXIF $norm['description'] - from XMP, IPTC, or EXIF $norm['creator'] - from XMP, IPTC, or EXIF $norm['rights'] - from XMP, IPTC, or EXIF $norm['createDate'] - from EXIF DateTimeOriginal
Plus access to raw metadata like $meta['Subject'], $meta['Make'], $meta['GPSLatitude'], etc.
