Gulp: Browser Sync Task

gulpfile.js

/**
 * Browser Sync
 *
 * Asynchronous browser syncing of assets across multiple devices!! Watches for changes to js, image and php files
 * Although, I think this is redundant, since we have a watch task that does this already.
*/
gulp.task('browser-sync', function() {
	var files = [
			'**/*.php',
			'**/*.{png,jpg,gif}'
		    ];
	browserSync.init(files, {

		// Read here http://www.browsersync.io/docs/options/
		proxy: url,

		// port: 8080,

		// Tunnel the Browsersync server through a random Public URL
		// tunnel: true,

		// Attempt to use the URL "http://my-private-site.localtunnel.me"
		// tunnel: "ppress",

		// Inject CSS changes
		injectChanges: true
