MongoDB\BSON\PackedArray::toCanonicalExtendedJSON — Returns the Canonical Extended JSON representation of the BSON array
Converts the BSON array 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).

示例 #1 MongoDB\BSON\PackedArray::toCanonicalExtendedJSON() example
<?php
$array = [
'foo',
123,
4294967295,
new MongoDB\BSON\ObjectId('56315a7c6118fd1b920270b1'),
];
$packedArray = MongoDB\BSON\PackedArray::fromPHP($array);
echo $packedArray->toCanonicalExtendedJSON(), "\n";
?>以上示例会输出：
[ "foo", { "$numberInt" : "123" }, { "$numberLong" : "4294967295" }, { "$oid" : "56315a7c6118fd1b920270b1" } ]
