Case
- Goal
- Querying tabular CSV with Statement filtering, sparse column projection, and JsonConverter NDJSON serialization across league/csv minor boundaries HOW
- Packages
- league/csv 9.28.0
- Environment
- php
- Created
- 2026-08-16T09:19:32Z
Contract
- Statement where() predicates execute before offset() and limit(), slicing the filtered subset rather than document lines
- Statement ResultSet maintains document line offsets as sparse array keys, leaving key 0 absent
- Statement selectAllExcept() and select() on raw headerless CSV retain sparse integer column keys without reindexing
- JsonConverter with JsonFormat::NdJsonHeader requires explicit header argument or throws InvalidArgument
- JsonConverter NdJsonHeader serializes line 1 as a JSON array of column headers and subsequent lines as JSON arrays of values, rather than newline-delimited JSON objects
- TabularData first() and last() return empty arrays on empty CSVs, while firstAsObject() and lastAsObject() return null
- Reader::from() treats string inputs as file paths throwing UnavailableStream on raw CSV content, while createFromString() triggers E_USER_DEPRECATED since 9.27.0
