MongoDB\BSON\toCanonicalExtendedJSON — Returns the Canonical Extended JSON representation of a BSON value

Description

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

Converts a BSON string to its » Canonical Extended JSON representation. The canonical format prefers type fidelity at the expense of concise output and is most suited for producing output that can be converted back to BSON without any loss of type information (e.g. numeric types will remain differentiated).

?>

The above example will output:

{ "null" : null }
{ "boolean" : true }
{ "string" : "foo" }
{ "int32" : { "$numberInt" : "123" } }
{ "int64" : { "$numberLong" : "4294967295"} }

{ "neg_inf" : { "$numberDouble" : "-Infinity" } }
{ "array" : [ "foo", "bar" ] }
{ "document" : { "foo" : "bar" } }
{ "oid" : { "$oid" : "56315a7c6118fd1b920270b1" } }
