## XMPReader
Reader for XMP data containing properties relevant to images, written in PHP.
### Usage
```php
composer require wikimedia/xmp-reader
```
```php
use Wikimedia\XMPReader\Reader as XMPReader;
//...
// Check if the php instance has the required supported libraries to parse XMP
$isXMPSupported = XMPReader::isSupported();
// Create a new instance
$xmp = new XMPReader();
// or
$xmp = new XMPReader( $logger, $filename );
// where $logger is an implementation of Psr\Log\LoggerInterface and $filename a string describing the origin of your XMP content
// To parse XMP data in $string
$xmp->parse( $string );
// To parse XMP Extended data in $string
$xmp->parseExtended( $string );
// To retrieve the parsed results
$results = $xmp->getResults();
```
The parsed results are returned in an array of 3 potential groups,
which indicate their priority according to the Metadata Working Group guidance.

```php
[
'xmp-exif' => [],
'xmp-general' => [],
'xmp-deprecated' => [],
]
