PHP 7.1.21 Released

MongoDB\BSON\toCanonicalExtendedJSON

(mongodb >=1.3.0)

MongoDB\BSON\toCanonicalExtendedJSONReturns the Canonical Extended JSON representation of a BSON value

说明

string MongoDB\BSON\toCanonicalExtendedJSON ( string $bson )

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).

参数

bson (string)

BSON value to be converted.

返回值

The converted JSON value.

?>

以上例程会输出:

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