The Boy/Girl Scout Rule

It’s not enough to write the code well. The code has to be kept clean over time. We’ve all seen code rot and degrade as time passes. So we must take an active role in preventing this degradation.

The Boy Scouts of America have a simple rule that we can apply to our profession.

Leave the campground cleaner than you found it.

If we all checked-in our code a little cleaner than when we checked it out, the code simply could not rot. The cleanup doesn’t have to be something big. Change one variable name for the better, break up one function that’s a little too large, eliminate one small bit of duplication, clean up one composite if statement.

Creating URL slugs properly in PHP (including transliteration for UTF-8)

The point to use a slug (semantic URL) besides of improve the SEO of your articles is to prevent that the user, at the creation of for example an article, it uses special characters that aren't allowed in a URL, appropiate the usage etc. What target usage means, is context dependent.

In this article, you'll learn how to slugify a string in PHP properly, including (or not) support (conversion) for cyrilic and special latin characters.

Slugify in PHP

The following function exposes a simple way to convert text into a valid slug:

	# Bash for loop
	for i in /etc/*; do
	echo "${i}"
	done

	# Same as above (alternate syntax)
	# also works with other loop structures
	for i in /etc/*
	do
	echo "${i}"

	<?php
	// src/YourApp/Bundle/YourBundle/Twig/ToArrayExtension.php

	namespace Appcito\Bundle\CoreBundle\Twig;

	/**
	* A simple twig extension that adds a to_array filter
	* It will convert an object to array so that you can iterate over it's properties
	*/
	class ToArrayExtension extends \Twig_Extension

	#!/bin/bash

	# thanks http://www.jenssegers.be/blog/46/deploying-websites-with-git-and-composer-

	# replace folder
	cd "`dirname $0`/../../application/config"

	# Check if a composer.json file is present
	if [ -f composer.json ]; then

	UPDATE tableA AS A
	LEFT JOIN tableB AS B on (A.name_a = B.name_b)
	SET
	A.update_date = B.insert_date

	;(function($, undefined) {
	$.extend({
	toUTF8 : function(text) {
	text = text.replace(/\r\n/g,"\n");

	var output = [];

	for (var n = 0 ; n < text.length ; n++) {
	var c = text.charCodeAt(n);
