How to Gracefully Convert an stdClass Object to a Custom Class in PHP?

Converting an stdClass Object to a Custom Class

The provided code snippet highlights a challenge when working with third-party systems that return stdClass objects. While casting the object to an array and passing it to a constructor is a viable solution, it raises questions about restoring the original object's class.

PHP provides type juggling capabilities that allow for conversions between different data types. However, these conversions are limited to primitive types such as integer, boolean, float, and string.

Custom Mapping

One approach to converting an stdClass object to a custom class is to create a mapper that transforms the object's properties into those of the target class. This involves defining rules for each property and ensures that the correct data is assigned to the new instance.

Hackish Solution

An alternative approach, albeit not recommended for production, is to use the "arrayToObject" function. This function takes an array as input and generates a serialized string that represents an instance of a specified class. The serialized string is then unserialized into the target class.

Object to Object Conversion

The concept of "objectToObject" conversion mirrors that of "arrayToObject." Here, the input is an existing object, and the output is an instance of a different class. The same method of manipulating the serialized string is employed, effectively transforming the object into the desired class.

Conclusion

While the provided solutions offer ways to convert stdClass objects to custom classes, it is essential to consider the limitations and potential drawbacks of each approach. Custom mapping provides a more robust and maintainable solution, while the hackish "arrayToObject" function is prone to unexpected behaviors and should be used with caution.
