Without Composer

[apmuthu]

Use php-exif without composer thus:

<?php
// Ref: https://github.com/PHPExif/php-exif
// Ref: https://github.com/LycheeOrg/php-exif supports video and altitude too

$path_to_exiflib = '../../libraries/PHPExif/';
require_once($path_to_exiflib.'Adapter/AdapterInterface.php');
require_once($path_to_exiflib.'Adapter/AdapterAbstract.php');
require_once($path_to_exiflib.'Adapter/Exiftool.php');
require_once($path_to_exiflib.'Adapter/Native.php');
require_once($path_to_exiflib.'Adapter/NoAdapterException.php');
require_once($path_to_exiflib.'Hydrator/HydratorInterface.php');
require_once($path_to_exiflib.'Hydrator/Mutator.php');
require_once($path_to_exiflib.'Mapper/MapperInterface.php');
require_once($path_to_exiflib.'Mapper/Exiftool.php');
require_once($path_to_exiflib.'Mapper/Native.php');
require_once($path_to_exiflib.'Reader/ReaderInterface.php');
require_once($path_to_exiflib.'Reader/Reader.php');
require_once($path_to_exiflib.'Exif.php');

$reader = \PHPExif\Reader\Reader::factory(\PHPExif\Reader\Reader::TYPE_NATIVE);
$exif = $reader->read('./test.jpg');

echo 'GPS: ' . $exif->getGPS() . PHP_EOL;
// 13.054053400000001,80.257204999722219
// https://www.google.com/maps/@13.0540534,80.257205,15z
// 15z is the zoom out factor

Get sample images with GPS data for testing from:

GPS and other meta tags are also available in videos and so is the Altitude parameter - all these are enabled in the the following fork:
https://github.com/LycheeOrg/php-exif
