Notes on programming-related problems that I’ve encountered while working on various projects.

Don’t Over-Architect Your Blog Posts

At some point, I lost the motivation to write about anything that would include too much code because of the amount of time it would take to:

  • put a functioning solution together,
  • architect it in such a way that’d fit with best practices (at least for OOP),
  • explain the various features about OOP that the reader may not know,
  • then explain the problem.

This is too complex.

I’m not saying that articles shouldn’t be written that explain the concepts of object-oriented programming or shouldn’t talk about certain rationale for why something was done.

Arguably, pun intended, one of the key pieces of command-line application is making sure that they are interactive through command-line arguments. In PHP, there are two variables to understand:

  • $argc is the number of arguments passed to script. Note the script’s filename is always passed as an argument to the script, therefore the minimum value of $argc is 1.
  • $argv is an array of arguments passed to script. Note the first argument $argv[0] is always the name that was used to run the script.

Writing PHP Command-Line Applications: A Basic Script

TL;DR: I’ve been writing PHP command-line scripts to help automate mundane tasks. As these tasks are growing in complexity or turning more into applications that interface with third-party APIs, I’m documenting the things I find important that others may also find helpful.

There are three things necessary to get a basic script up and running on your local machine (assuming you already have PHP installed):

  1. Know the path to the PHP binary,
  2. Make sure your script references said binary,
  3. And make the script executable.
