MongoDB\BSON\toJSON — Returns the Legacy Extended JSON representation of a BSON value
This function has been DEPRECATED as of extension version 1.20.0 and was removed in 2.0. Applications should use MongoDB\BSON\Document::toCanonicalExtendedJSON() or MongoDB\BSON\Document::toRelaxedExtendedJSON() instead.
Converts a BSON string to its » Legacy Extended JSON representation.
Note: There exist several JSON formats for representing BSON. This function implements the "strict mode" defined in » MongoDB Extended JSON, which has been superseded by the canonical and relaxed formats defined in the » Extended JSON Specification and implemented by MongoDB\BSON\toCanonicalExtendedJSON() and MongoDB\BSON\toRelaxedExtendedJSON(), respectively.
» JSON does not support
NAN and
INF and
MongoDB's Legacy Extended JSON format does not define an alternative
representation for these values
(» libbson will output
nan and inf literals, which may not be
parsed as valid JSON). If you are working with BSON that may contain
non-finite numbers, please use
MongoDB\BSON\toCanonicalExtendedJSON() or
MongoDB\BSON\toRelaxedExtendedJSON().
