Note:
PHP implements a superset of JSON as specified in the original » RFC 4627 - it will also encode and decode scalar types and
NULL
. RFC 4627 only supports these values when they are nested inside an array or an object.Although this superset is consistent with the expanded definition of "JSON text" in the newer » RFC 7159 (which aims to supersede RFC 4627) and » ECMA-404, this may cause interoperability issues with older JSON parsers that adhere strictly to RFC 4627 when encoding a single scalar value.
