#PHPExiftool

PHP Exiftool is an Object Oriented driver for Phil Harvey's Exiftool (see http://www.sno.phy.queensu.ca/~phil/exiftool/). Exiftool is a powerfull library and command line utility for reading, writing and editing meta information written in Perl.

PHPExiftool provides an intuitive object oriented interface to read and write metadatas.

You will find some example below, but I strongly recommend you to read the full documentation.

This driver is not suitable for production, it is still under heavy development.

##Exiftool Reader

<?php

use PHPExiftool\Reader;
use PHPExiftool\Driver;

$Reader = new Reader();

$Reader
  ->in(array('documents', '/Picture'))
  ->extensions(array('doc', 'jpg', 'cr2', 'dng'))
  ->exclude(array('test', 'tmp'))
  ->followSymLinks();

foreach ($Reader as $MetaDatas)
{
    echo "found file " . $MetaDatas->getFile()->getPathname() . "\n";

    foreach ($MetaDatas as $metadata)
    {
        if ($metadata->getValue() instanceof Driver\Value\Binary)
        {
            echo sprintf("\t--> Field %s has binary datas" . PHP_EOL, $metadata->getTag());
        }
        else
        {
            echo sprintf("\t--> Field %s has value(s) %s" . PHP_EOL, $metadata->getTag(), $metadata->getValue());
        }
    }
}

##Exiftool Writer

<?php

use PHPExiftool\Writer;
use PHPExiftool\Driver\Metadata;
use PHPExiftool\Driver\MetadataBag;
use PHPExiftool\Driver\Tag;
use PHPExiftool\Driver\Value;

$Writer = new Writer();

$bag = new MetadataBag();
$bag->add(new Metadata(Tag\IPTC\ObjectName(), new Value\Mono('Subject')));

$Writer->write('image.jpg', $bag);
