Gulp LiveReload for PHP files, wont't refresh browser - gulp

Question

Building myself a gulpfile.js for a WordPress theme. Currently all the JS and CSS is working perfectly, and livereload is reloading on css/js change.
But I also want to refresh the browser whenever a PHP file is changed. I did some searching and found the following snipped which I'm using within my gulpfile.js
gulp.task('watch', function(){
// Listen on port 35729 for LiveReload
server.listen(35729, function (err) {if (err) {return console.log(err) };
gulp.watch("assets/scss/**/*.scss", ['sass']); // Watch and run sass on changes
gulp.watch("assets/js/_*.js", ['javascripts']); // Watch and run javascripts on changes
gulp.watch("assets/img/*", ['imagemin', 'svgmin']); // Watch and minify images on changes
gulp.watch('**/*.php').on('change', function(file) {
util.log('PHP FILES CHANGED!');
server.changed(file.path);
});
});
});
Whenever I change a PHP file I can see "PHP FILES CHANGED!" in the console, but livereload does not update the browser. What am I missing?

Did some further research and testing, and it turns there's no point in using tiny-lr since gulp-livereload does everything. So I changed my tasks to do the reloading by .pipe(livereload()); – and changed my watch task to the following:
gulp.task('watch', function(){
var server = livereload();
gulp.watch('**/*.php').on('change', function(file) {
server.changed(file.path);
util.log(util.colors.yellow('PHP file changed' + ' (' + file.path + ')'));
});
gulp.watch("assets/scss/**/*.scss", ['sass']); // Watch and run sass on changes
gulp.watch("assets/js/_*.js", ['javascripts']); // Watch and run javascripts on changes
gulp.watch("assets/img/*", ['imagemin', 'svgmin']); // Watch and minify images on changes
});

There's a shorter solution that maybe useful to those using gulp-livereload. There's a reload method that can be triggered. Like so:
gulp.task('watch', function(){
livereload.listen();
gulp.watch('source/*.php', livereload.reload);
});
