Labs

Labs are hands-on coding projects that you build along with Tonya as she explains the code, concepts, and thought processes behind it. You can use the labs to further your code knowledge or to use right in your projects. Each lab ties into the Docx to ensure you have the information you need.

Each lab is designed to further your understanding and mastery of code. You learn more about how to think about its construction, quality, maintainability, programmatic and logical thought, and problem-solving. While you may be building a specific thing, Tonya presents the why of it to make it adaptable far beyond that specific implementation, thereby giving you the means to make it your own, in any context.

Character Set Encoding – It Matters!

Character set encoding matters as many language characters are not part of the standard ASCII character set. Instructions such as strlen will not behave the way you think when using it with extended characters such as €, ©, ®, à, ë, and many others. And languages such as Mandarin and Russian require a different approach when working with strings. In this episode, let’s talk about why the encoding matters and how the character set is really represented in the computer. Hint: Everything in the computer breaks down into binary, i.e. ones and zeros. Simple string instructions like strlen use bytes. […]

Lab Introduction

Let’s introduce you to what you’ll be doing in this hands-on lab. You will be building a plugin that houses different utility functions. In this lab, you’ll be working on string processing and checking functions. You’ll build reusable functions that you can use on every project…to save you time.

Doing More With PHP String Processing

There are many times when we need to more complex processing with strings. PHP provides us with the instructions we need to verify and manipulate strings. In this hands-on lab, you will continue learning about processing strings in PHP.

Specifying Which Argument in a Formatted String

What if you need to repeat one of the arguments within the formatted string? You could repeat the argument in the list again like this: But then that’s a WET pattern, as you are repeating code. Instead, PHP lets you specify which argument you want for each of the placeholders. Resources sprintf – in Docx sprintf – PHP Manual printf – PHP Manual Type Casting

Embedding Complex Variables

In the last episode, I had you wrap the embedded variable within curly braces. Why? Readability. Yes, you can omit the curly braces with a simple variable embed. However, to me, it’s less readable. Therefore, I advocate always using the curly braces like this: “My name is {$first_name}.” How do you embed an element from an associative array or object? These embeds are known as complex variables. For these, you must wrap the variable within curly braces. In this episode, you will walk through embedding an associative array element within a string.
