How to Concatenate PM and CM Strings in a Multi-Dimensional Array Using PHP

Are you working with a multi-dimensional array in PHP and need to concatenate specific strings like PM and CM? You're not alone! Many developers encounter this requirement, especially when dealing with arrays where certain values must have specific suffixes while ensuring the conditions are met. In this guide, we will go through a detailed guide on how to achieve this in PHP.

Understanding the Problem

The challenge is to concatenate two strings, PM and CM, to the elements within a multi-dimensional array according to specific rules:

Each sub-array must contain at least one occurrence of PM and one occurrence of CM.

Maximum occurrences are capped at two each for any single name.

The strings must be added separately; hence a single element cannot be suffixed with both at the same time.

Example Scenario

Let’s illustrate this with a sample array:

Step-by-Step Solution

Here’s how to implement this in PHP:

Step 1: Initialize a Counting Array

First, we will set up an associative array to track how many PM and CM concatenations have been made:

Step 2: Define a Recursive Function for Random Selection

We need a function that will randomly select an index for concatenation while adhering to the rules regarding limits and exclusions:

Step 3: Process Each Sub-array

Using a loop, iterate through each sub-array to apply the concatenation logic. This will involve selecting the appropriate keys for PM and CM concatenation:

Conclusion

The above PHP code successfully concatenates the required strings under the specified conditions. Although the approach might seem a bit complex, it effectively ensures that each name adheres to the desired structure.
