How to right join in PHP?

PHP right join code

In PHP, you can perform a right join operation between two arrays or data sets by iterating through one array and matching its elements with elements in another array based on a specified condition. Here’s an example of how you can implement a right join operation in PHP:


In this example, we have two arrays, $leftArray and $rightArray, representing tables you want to right join. We iterate through the right array and check if there’s a matching item in the left array based on a specified condition (in this case, matching id values). If a match is found, we merge the data from both arrays into a single result array. If no match is found in the left array, we include the right item with null values for the left side. Finally, we print the result array.
