Personal opinions and how-to’s that I’ve written both here and as contributions to other blogs.

Adding Multiple Coding Standards with Composer

July 24, 2019 / Tom

It’s one thing to be using PHP CodeSniffer manually but if you’re using a utility such as GrumPHP to check your work before committing it to the repository, then you’re likely going to want to use the version that you’re installing with your project.

This assumes that:

You are installing PHP CodeSniffer local to your project,
You want to install a specific set of coding standards to run against your code.

Remember, this is also done in the context of wanting to run automated scripts during the commit process and in a local environment (versus a global setting) with Composer.

How To Remove Images with DOMDocument

July 9, 2019 / Tom

I’ve written about DOMDocument in a few other posts (1, 2, 3 to share a few) but I continue to find it useful in different ways.

Remember, DOMDocument is a class in PHP that allows us to manipulate the HTML document before rendering it in the browser.

From the manual:

Represents an entire HTML or XML document; serves as the root of the document tree.

Whenever I think of working with the saveHTML function, I think of needing to serialize the new information into a file or other output stream before sending it to the browser.

But we don’t have to do that. It can be done in memory.

The Difference in cURL and WordPress Requests

July 1, 2019 / Tom

cURL is a very popular PHP library that I’ve referenced in several posts other posts (1 and 2, for example). And it’s one that I think should be reviewed, explored, and possibly used by anyone working in PHP (yes, even those working in WordPress).

But because of the native WordPress APIs, we do have a level of abstraction that allows us to achieve much of the same functionality (if not the same functionality).

Specifically, I’m talking about wp_safe_remote_get.

This function is ideal when the HTTP request is being made to an arbitrary URL. The URL is validated to avoid redirection and request forgery attacks.

I specifically mention the safe variant of this function for the definition above (there is another variant, but it’s important to take precautions against arbitrary URLs for security reasons).

When The Browser and Terminal Show Different Versions of PHP

June 20, 2019 / Tom

If you happen to see two different versions of PHP whenever you run:

php -v in the console and visit
phpinfo() in the browser

Then this usually means the version of PHP that your web server is using is different than the version of PHP your command-line is using.

Specifically, this means you likely have more than one installation, and the web server is using one version, and the terminal is using a different version (in addition to using a CLI version of the interpreter).

Of course, if you’re seeing the browser and the terminal show different versions of PHP then something is wrong. You want them to be the same, but depending on how your system is configured, then you may need to update your environmental variables.

I was recently having issues with this with various installations of PHP installed via Homebrew and with my local installation of Valet.

This is what I did to fix it.

A Return to Form (Over a Decade in the Making)

June 18, 2019 / Tom

I don’t know how many people are considered “regular readers” of this site (let alone any site, to be honest) because social media has changed how we find content, save it, and read it.

But if you’re someone who browses this site on any regular basis, then you’ve likely noticed that I’ve not posted anything related to development for a couple of weeks now.

Nothing’s wrong; life is good. But I’ve been taking a step back on several things in which I’m involved to take stock of essentially:

what I’m doing,
why I’m doing it,
what I want to continue to do,
and why I want to do it.

And if you were around when blogging was what it was, say, five years ago, then you know it’s considered “bad form” talk about not blogging and to get all apologetic about it.

I’m not getting apologetic about it, though.

Instead, I’m providing an update as to what I plan to do with this site moving forward.

And no, it’s not the type of post that contains anything related to WordPress development or programming.
