Pros & Cons
Pros
Uses PHP streams to handle large CSV files scalably, preventing memory exhaustion as highlighted in the documentation for reading and writing.
Offers robust filtering and array-to-object mapping capabilities, enabling complex data manipulation without extra dependencies.
Converts CSV data into JSON, XML, or HTML outputs, simplifying integration with various systems, as noted in the features.
Fully documented with a dedicated website and unit-tested, ensuring reliability and ease of use for developers.
Cons
Requires the ext-filter extension, which may not be enabled in all PHP installations, adding a setup step that isn't always straightforward.
