Installing Multiple Coding Standards There's an interesting challenge that comes if you want to configure multiple coding standards with PHPCS.

I’ve talked about the importance of using coding standards (whatever standard you opt to use it up to you) and how to get PHP CodeSniffer (especially with Visual Studio Code) set up in several posts.

But there’s an interesting challenge that comes if you want to configure multiple coding standards with PHPCS. And this isn’t that strange a scenario, either.

Imagine you have several different projects on which you’re working – one uses WordPress’ coding standards, one uses PSR2, and one uses some other set of rules defined by the organization for which you work.

And you want to add them all as options to your configuration.

Using cURL to Determine If the Specified URL Is a Valid Page Another useful feature of cURL: Determining if the specified URL takes you to a valid page.

Earlier this month, I wrote about finding the destination of a redirect using cURL in PHP. This can be a useful function to use whenever:

  • you know the URLs with which you’re dealing are going to redirect,
  • you know that the number of redirects will be limited to one.

Granted, in the latter case, it’s becoming more difficult because sites like, say, Twitter, have multiple redirects before you get to the destination.

But that’s a topic for another post (unless you just want to implement a recursive or iterative way of working through requests until you find the final destination).

Anyway, there’s another thing that can also be useful whenever you’re working with redirects and with cURL, and that’s determining if the specified URL takes you to a valid page.

How to Manipulate the DOM Using PHP Manipulating the DOM on the client-side isn’t always the best option. We can do so using built-in features of PHP.

When it comes to manipulating the DOM, the first thing many of us likely think of is using JavaScript to do whatever it is we need to do.

Not only does the language natively support functions for doing this, newer features of ES6 give us more powerful ways to build client-side scripts. And if you’re using jQuery with WordPress, then you have the same library of functions for, ahem, querying the DOM that we’ve had for years.

But manipulating the DOM on the client-side isn’t always the best option. Instead, you may want to do so on the server-side. And because of some of the features built into PHP, it’s not much different from how we do things using JavaScript.

Other than, of course, we’re doing so on the server.

Finding the Destination of a Redirect with PHP This solution for finding the destination of a redirect with PHP is easy but it assumes a single redirect.

Recently, I was working on a project that was communicating with a third-party API that, like many APIs, sends back a lot of data part of which includes a URL for the product associated with the API.

The thing about the API that was being returned was not the proper destination URL. Instead, it was a URL that ultimately redirected to another URL.

So imagine hitting, say, acme.site-info.com and having it direct to acme.com. We do this manually all the time, but I needed to get the actual – or the final – destination of the direct from the URL.

And finding the destination of a redirect with PHP is easy; however, this does assume there’s only a single redirect.

Nonetheless, here’s how to do it.

WordPress Class Serialization with PHP Using the JsonSerializable Interface, adding WordPress class serialization is really easy.

If you’re used to working with models (in any foundation or framework, but specifically WordPress), then there’s a chance that you may need to serialize an instance of the model at some point.

Sure, writing the class to a database using PHP’s built-in functions is easy enough; however, introducing a bit of flexibility especially as it relates to making it available on other platforms is important.

For example, let’s say you’re building an application on WordPress that’s going to have some type of unique piece of information represented in a model. The model will then be accessible via a mobile application through the REST API.

WordPress Class Serialization: PHP

Arguably, one of the easiest ways to get this done is to use JSON. It’s a format that works across various languages and platforms, can be easily serialized and de-serialized by said platforms, and sent across the wire as needed.

And it’s incredibly easy to implement this in PHP. You just need to make sure your class implements the JsonSerializable interface.

WordPress Class Serialization: PHP

From the documentation, the interface does the following:

Objects implementing JsonSerializable can customize their JSON representation when encoded with json_encode().

The only method a class needs to provide is jsonSerialize, and though it’s likely you will want to serialize all of the properties of an object (as well as its state whenever its called), you can customize the implementation however you’d like.
