(mongodb >=1.3.0)

MongoDB\BSON\toRelaxedExtendedJSONReturns the Relaxed Extended JSON representation of a BSON value

说明

string MongoDB\BSON\toRelaxedExtendedJSON ( string $bson )

Converts a BSON string 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.

参数

bson (string)

BSON value to be converted.

返回值

The converted JSON value.

?>

以上例程会输出:

{ "null" : null }
{ "boolean" : true }
{ "string" : "foo" }
{ "int32" : 123 }
{ "int64" : 4294967295 }
{ "double" : 1.0 }
{ "nan" : { "$numberDouble" : "NaN" } }
{ "pos_inf" : { "$numberDouble" : "Infinity" } }
{ "neg_inf" : { "$numberDouble" : "-Infinity" } }
{ "array" : [ "foo", "bar" ] }
{ "document" : { "foo" : "bar" } }
{ "oid" : { "$oid" : "56315a7c6118fd1b920270b1" } }
{ "dec128" : { "$numberDecimal" : "1234.5678" } }
