How to Build a PHP API to Display Server Status in JSON Format

In the world of web development, APIs are crucial for different services to communicate. However, creating an effective API can often be tricky, especially when it comes to formatting the output correctly. Have you ever tried to build an API to check the status of your servers? If so, you might have encountered difficulties in structuring the output, particularly regarding multidimensional arrays in JSON format. Fear not! In this guide, we'll walk through how to create a PHP API that fetches server statuses and returns a properly formatted JSON response.

The Challenge: Displaying Server Status

You may have attempted to create an API and found that your raw code was returning a messy array when you wanted a structured JSON response like this:
