MongoDB\BSON\Document::toRelaxedExtendedJSON

Returns the Relaxed Extended JSON representation of the BSON document

&reftitle.description; final public `string` `MongoDB\BSON\Document::toRelaxedExtendedJSON`

Converts the BSON document to its Relaxed Extended JSON representation. The relaxed format prefers use of JSON type primitives at the expense of type fidelity and is most suited for producing output that can be easily consumed by web APIs and humans.

&reftitle.parameters; &no.function.parameters;
&reftitle.returnvalues;

Returns a string containing the Relaxed Extended JSON representation of the BSON document.
