Introduction

If you're working with the Zend Framework and find yourself in a situation where you need to merge a Zend_Db_Table_Rowset with an array of objects, you may run into a challenge. By default, calling $myRowset->toArray(); simply converts the rowset to a standard array, not to objects. This can be problematic if you require the data to be in object format for further manipulation.

In this post, we’ll explore an effective solution to convert Zend_Db_Table_Rowset into an array of objects, which can then be easily merged with other object arrays.

The Problem

You're looking to perform a merge between a Zend_Db_Table_Rowset and an array of instantiated objects, such as:

However, simply converting the rowset using $myRowset->toArray() doesn't work—your end goal is to have an array consisting of objects.

Here’s a snippet showing your initial approach:

While the above works, there’s a more elegant way to achieve this with less code.

The Solution

To effectively convert the Zend_Db_Table_Rowset into an array of objects, you can use the iterator_to_array function. This function takes an iterable and converts it directly into an array. Here’s how to implement it:

Step-by-step Guide

Fetch the Rowset:

Conclusion

By using the iterator_to_array function, you can efficiently convert a Zend_Db_Table_Rowset into an array of objects, making it easy to merge with other arrays of objects. This concise solution not only simplifies your code but also enhances its readability.

With this approach, you can easily handle complex data manipulations and keep your codebase clean and efficient. Happy coding!
