How Can I Efficiently Merge PHP Objects Without Subclassing?

Merging PHP Objects: An Efficient Approach

When dealing with PHP5 objects that lack a subclass relationship, merging their content can pose a challenge. In this article, we'll explore the most efficient method for achieving this.

The traditional solution of copying objects into arrays can be resource-intensive if the objects contain a large number of fields. A better approach involves utilizing the array_merge() function to combine the arrays representing each object:

$obj_merged = (object) array_merge((array) $obj1, (array) $obj2);

This technique effectively merges the fields of both objects into a new object. Interestingly, it remains valid even when the objects have methods, as demonstrated by tests conducted in PHP versions 5.3 and 5.6.

By employing this efficient method, developers can seamlessly merge PHP objects, regardless of their size or the presence of methods.
