As developers, we need to build and process dynamic strings. Our code pulls in information from various sources, assembles it, and then renders it out to the browser. PHP provides a powerful function library to help us. In this hands-on lab, you will learn about the basics of PHP string building and processing.
What Will You Learn?
In this hands-on lab, you and I are going to ease into programming. You’ll learn about:
- Concatenating strings together
- Difference between
sprintfandprintf - Rendering strings out to the browser
- Checking for and finding substrings
- Replacing character or substrings
- Stripping out characters or entities
- Counting characters or length
- and more
Prerequisites
You will be writing code in this lab. You’ll need to have a basic local web development set up and ready to go. You can refer to this article in the Help Center to set up your local sandbox test website.
Create a dummy post called “WordPress Rocks”. Then populate the content using this post with the content from this gist.
Who needs copy/paste? Right. Writing code from scratch is fun!
