Simple extension to read barcodes from images

Upgrade at 2018-12-05

Support PHP7, And fix some bug that may cause crash.

Basic usage:

<?php
/* Create new image object */
$image = new ZBarCodeImage("test.jpg");

/* Create a barcode scanner */
$scanner = new ZBarCodeScanner();

/* Scan the image */
$barcode = $scanner->scan($image);

/* Loop through possible barcodes */
if (!empty($barcode)) {
	foreach ($barcode as $code) {
		printf("Found type %s barcode with data %s\n", $code['type'], $code['data']);
	}
}
?>

The EAN13 image in the tests/ directory is from http://en.wikipedia.org/wiki/File:Ean-13-5901234123457.png
