PHP-Exiftool

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

Installation

The recommended way to install PHP-Exiftool is through composer.

{
    "require": {
        "phpexiftool/phpexiftool": "~0.1.0"
    }
}

Usage

Exiftool Reader

A simple example : how to read a file metadatas :

<?php

require __DIR__ . '/vendor/autoload.php';

use Monolog\Logger;
use PHPExiftool\Reader;
use PHPExiftool\Driver\Value\ValueInterface;

$logger = new Logger('exiftool');
$reader = Reader::create($logger);

$metadatas = $reader->files(__FILE__)->first();

foreach ($metadatas as $metadata) {
    if (ValueInterface::TYPE_BINARY === $metadata->getValue()->getType()) {
        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()->asString());
    }
}

An example with directory inspection :

use Monolog\Logger;
use PHPExiftool\Reader;
use PHPExiftool\Driver\Value\ValueInterface;

$logger = new Logger('exiftool');
$Reader = Reader::create($logger);

$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() . "\n";

    foreach ($MetaDatas as $metadata) {
        if (ValueInterface::TYPE_BINARY === $metadata->getValue()->getType()) {
            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()->asString());
        }
    }
}

Exiftool Writer

use PHPExiftool\Writer;
use PHPExiftool\Driver\Metadata;
use PHPExiftool\Driver\MetadataBag;
use PHPExiftool\Driver\Tag\IPTC\ObjectName;
use PHPExiftool\Driver\Value\Mono;

$Writer = Writer::create();

$bag = new MetadataBag();
$bag->add(new Metadata(new ObjectName(), new Mono('Pretty cool subject')));

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