MongoDB\BSON\toJSON — Returns the Legacy Extended JSON representation of a BSON value

Açıklama

MongoDB\BSON\toJSON ( string $bson ) : string

Converts a BSON string to its » Legacy Extended JSON representation.

Bilginize: 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 This function implements the "strict mode" defined in » MongoDB Extended JSON, which has been superseded by the canonical and relaxed formats defined in the » Extended JSON Specification and implemented by MongoDB\BSON\toCanonicalExtendedJSON() and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.

Uyarı

» 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().
