MongoDB\BSON\Document::toCanonicalExtendedJSON

Returns the Canonical Extended JSON representation of the BSON document

説明

final public string MongoDB\BSON\Document::toCanonicalExtendedJSON()

Converts the BSON document 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).

パラメータ

この関数にはパラメータはありません。

戻り値

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

foreach ($documents as $document) {
    $bson = MongoDB\BSON\Document::fromPHP($document);
    echo $bson->toCanonicalExtendedJSON(), "\n";
}

?>

上の例の出力は以下となります。
