DeepCopy is a PHP library that creates deep copies of objects.
The library solves the problem of shallow copying in PHP, where cloning an object by default only copies the object itself while leaving nested objects and arrays as references to the originals. DeepCopy recursively traverses an object's properties and creates independent copies of all nested objects and arrays, ensuring that the cloned object and all its dependencies are completely independent from the original.
Developers should choose DeepCopy when working with complex object hierarchies where modifications to nested structures must not affect the original object. It suits projects that manipulate data models with deep nesting, such as those handling configuration objects, domain entities with relationships, or any scenario where true object isolation is required. The library is particularly valuable in codebases where accidental mutations of shared references could introduce subtle bugs.
The project maintains a focused scope with straightforward implementation. Development activity shows consistent engagement with the codebase through regular updates and maintenance of the core functionality.
