Unconventional Autoloaders (Talk)

We use autoloaders in PHP all the time, but if you change your mindset a little, you’ll find they can do a lot more than you might’ve thought. We’ll be taking a look at using some unconventional techniques, we can use autoloaders to take PHP a step further, introducing interesting and exciting new functionality PHP natively doesn’t support.

Translated Text in Source Code

by Liam Hammett · 8 minute read · #localisation

There are a few different ways to handle translated text in your codebase, but here we’ll cover 2 of the more common approaches; using the full text in your source code, and using translation keys.

⚠️ Note: This is an excerpt from my upcoming book & course about localisation for software developers. If you want more of this kind of content, sign up to the newsletter at l10n.expert to get more excerpts before the full release.

Protecting Against Infinite Gmail Addresses Using Regex

by Liam Hammett · 3 minute read · #php #regex #gmail

You might be aware that one Gmail account could have an almost unlimited number of email addresses associated with it, to no effort of the user who owns the account. If you’re not aware of this, check out my post below explaining it:

If you’re thinking to yourself “how can I protect against users abusing this in my own applications?” - you’re in luck, because that’s exactly what we’ll be covering here.

Compound Colour Utilities with TailwindCSS

by Liam Hammett · 5 minute read · #tailwind

When creating UIs with TailwindCSS, I often find myself writing the same few utilities together on the same elements all the time. This is why I often end up composing some common components, like a .button and .form-input classes.

In my mind, however, a “component” is a fully-formed set of styles for an element - something like a button may affect the colours, padding, border radius, text size and more - styles that are not necessary to be coupled together to still have a usable element.

But what do you do if you want to modify something that’s tightly coupled together, like the colours? If your default element has black text and you set a dark background utility, you probably don’t want it to keep having black text - coupling another text-colour utility to it.

Unconventional PHP (Talk)

by Liam Hammett · 1 minute read · #php #talk

You might think you know PHP, but if you dig below the surface you might find it can do more than you knew. Beyond the documented features, there lies a world of tricks, hacks and other techniques that can allow PHP to go a step further.

In this talk we’ll look outside the box at some things PHP provides like references, autoloading and magic methods and explore how using them in an unconventional way can benefit our own code.

Static Constructors in PHP

by Liam Hammett · 5 minute read · #php

“Static constructors” are a concept a lot of object-oriented programming languages support - although, unfortunately, PHP does not.

If you’re not familiar with the concept, a static constructor is just a method the developer can define on a class which can be used to initialise any static properties, or to perform any actions that only need to be performed only once for the given class. The method is only called once as the class is needed.

The C# guide about static constructors is a good resource to see how another language handles these, however we’ll cover the important bits below.

Laravel Testing - CSS Selector Assertion Macros

by Liam Hammett · 7 minute read · #laravel #testing

Laravel offers some very useful ways to test that your pages are being rendered with the right content by making assertions directly on the response object.

It’s such an elegant and fast way to be sure your application is doing what you want, but doesn’t necessarily always do what you might want.

A test doing this in Laravel may look like the following, creating an article then making sure the title of that article shows on the listing page:

Laravel Mixins

by Liam Hammett · 4 minute read · #laravel

Have you ever wished that a PHP class had another method on it that you’d like to use? Laravel makes this dream come true through its concept of “Macroable” classes.

Macroable itself is the name of a trait Laravel comes with that is applied to many of the framework’s own classes.

This trait allows you to call a static “macro” method at runtime to add a new method to the class by executing a closure. Behind the scenes, it will use the magic __call() and __callStatic() methods PHP provides to make the method work as if it were really on the class.

Textarea Slots in Vue Components

by Liam Hammett · 3 minute read · #vue

If you’ve ever tried to build a custom component to wrap around the <textarea> element with Vue, you’ll find that it’s not as simple as you first think to keep the behaviour the same as the native element.

In this post I’m going to quickly show the problem that you’ll likely run into, and a simple solution for it.

Let’s take a look…

Run and stop multiple long-running commands from Bash with a trap

by Liam Hammett · 7 minute read · #bash #laravel #cli

Sometimes when working on a project, I’ll always want to run a handful of commands at the same time, some of which may return when they’re done, others might be long-running, like watchers or services actively exposing ports.

This is something that might seem simple to do with a basic Bash script at first, but what if your script has multiple processes running side-by-side and you want to be able to stop them all at once too?

Here we’re going to take a look at how we can achieve this with Bash traps and the single-ampersand operator.

Private Constructors

by Liam Hammett · 5 minute read · #php #oop

Private constructors are a pattern found in object-oriented programming languages that prevents the class from being instantiated, except by itself.

The first time I saw this pattern in my programming career, I was confused. It wasn’t immediately apparent why such a feature would ever be beneficial in the real world. How are you meant to use the class if it can’t be instantiated? Why even bother defining a constructor at all if it can’t be called?

It turns out there are a handful of uses that private constructors can lend themselves to. Here I’m going to go over a few purposes they serve. The examples are in PHP but should transfer to any language that supports this feature.

My PHP Wishlist

by Liam Hammett · 10 minute read · #php #wishlist

Back when I started using PHP properly in the early 5.0 days, it felt like the language was pretty basic. Other languages were making leaps and bounds every year, and as time went on, PHP seemed to have stagnated. The language wasn’t bad, but it wasn’t as good as it could’ve been.

That all changed this decade. PHP has come an awful long way in the last few years and is once again proving that it’s got what it takes to be a programming language people should take seriously, even outside the web. I’m hugely happy with the direction PHP has taken and the amazing work of the core contributors and the entire ecosystem.

That said, there are a handful of things I would love to see PHP implement at some point in the future. These are a few things that I would’ve liked to be able to use every now and again when the circumstances for them come up.
