How to Efficiently Find the Highest Value in a Multidimensional PHP Array?

Finding the Highest Value in a Multidimensional Array

When working with complex multidimensional arrays, retrieving the highest value can be challenging. One common approach is to create a new array containing only the desired values (e.g., "Total") and then use the built-in max() function. However, this method involves additional steps and can be inefficient.

A more efficient solution is available using PHP's array_column function, introduced in version 5.5. This function allows you to extract an array of values corresponding to a specific key in a multidimensional array.

To achieve your goal, you can simply use the following snippet:

$highestTotal = max(array_column($array, 'Total'));

This will return the maximum value for the "Total" key within the array. The retrieved value represents the highest "Total" value in the multidimensional array.
