Best practices, structuring of code, dissecting algorithms and talking about the “Why?”

Creating Enumerations in PHP

If you are experienced in any of the major programming languages (.NET, Java, Python etc.) you are probably familiar with the idea of "Enums" or "Enumerations". These are used to help increase readability by assigning readable names to a collection of static values. It is much easier to read "Color.Red" than seeing "#FF0000" or "1". To expand on this idea imagine writing an if statement where you would compare a ...

Exception Handling With A Level of Abstraction

One of the common topics you always see in programming articles is the one about proper use of exception handling and the try/catch mechanism (if supported by your language of choice). As you absorb the wisdom of the sacred text, looking for that nugget of information about how to do it properly, you almost always come across the idea of abstraction. The incantation often reads something like "Throw exceptions at ...

Minimalism in Code

You may have heard of minimalism before in all sorts of disciplines and philosophies of life. Some of you might have heard of it as living without many possessions or perhaps in computing to refer to using as least amount of hardware and software resources as possible. I would like to take a small spin on perspective of applying this philosophy of life and apply it to writing code. While ...

NULL is Legit When Used Correctly

I was doing some research on a topic about compulsory parameters to constuctors for a project I was doing when I came across a topic about the use of NULL as a return value. Don't ask me how I stumble into these things. As you can imagine, as with everything in software engineering circles, there was a raging debate about whether or not NULL (or its equivalents like None in ...

Generating JSON Web Tokens (JWT) in Java or PHP

JSON Web Tokens (JWTs) are a mechanism for authentication that is simple to setup and easy to use. However, most of the time when you encounter this topic in a project, you get the advice to just use a JWT package. I am not quite sure why given that creating a token is relatively straight forward if you know how they are built. You can also implement such logic in ...

WordPress in the Enterprise – The Functions File

We covered the topic of linking your company's proprietary code library to WordPress in an earlier article, but those classes are generally for high level services, integrations and multi-project utility classes only. Examples of classes you might find there would be a class for making Application Programming Interface (API) calls to a customer relational management (CRM) system, a system logger or event classes for validation of data like emails and ...
