How to Convert Array to Group Keys and Group Values in PHP

Managing data structures is a fundamental task in programming, especially in PHP. A common challenge arises when you need to manipulate arrays, such as converting an associative array with keys and values into a structured format that groups them distinctly. If you've found yourself wondering how to achieve this, you're not alone! In this guide, we'll explore how to take an associative array and convert it into a grouped structure for better data management.

The Problem

Imagine you have an array structured as follows:

Your goal is to transform this array into a more organized format where the keys and values are grouped into separate arrays. You want the output to look like this:

This format is not only easier to read but also more convenient for various applications, such as data visualization with charting libraries.

The Solution

Let's break down the solution into easy steps. The primary goal is to create two arrays: one for the keys and another for the corresponding values converted to integers. We use the built-in PHP functions array_keys() and array_values() to extract this information, along with array_map() for type conversion.

Step-by-Step Solution

Here’s how to achieve the desired result:

Create Your Initial Array: Start by defining your associative array.

Extract the Keys and Values: Utilize array_keys() to get the keys and array_values() to get the associated values.

Convert Values to Integers: Use array_map() to apply the intval function, which converts the string representations of the numbers into actual integers.

Combine the Results: Encapsulate the results in a new array, using the desired structure with "labels" and "points".

Output the Result: Finally, use json_encode() to convert the entire array to a JSON string for easy output.

Here is the complete code:

Output

When you run this code, it will produce the following JSON output:

Conclusion

By following the steps outlined above, you can easily convert an associative array into a more structured format with clearly grouped keys and values in PHP. This method not only makes your data more accessible but also enhances interactivity when presenting it in user interfaces or reports.

Feel free to experiment with the above code and adapt it for your specific applications. Happy coding!
