    MongoDB\BSON\Document::toCanonicalExtendedJSON

    (mongodb >=1.16.0)

    MongoDB\BSON\Document::toCanonicalExtendedJSON — Returns the Canonical Extended JSON representation of the BSON document

    Description

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

    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).

    Exemple #1 MongoDB\BSON\Document::toCanonicalExtendedJSON() example

    <?php

    $documents     = [
    [     'null' => null ],
    [     'boolean' => true ],
    [     'string' => 'foo' ],
    [     'int32' => 123 ],
    [     'int64' => 4294967295 ],
    [     'double' => 1.0, ],
    [     'nan' => NAN ],
    [     'pos_inf' => INF ],
    [     'neg_inf' => -INF ],
    [     'array' => [ 'foo', 'bar' ]],
    [     'document' => [ 'foo' => 'bar' ]],
    [     'oid' => new MongoDB\BSON\ObjectId('56315a7c6118fd1b920270b1') ],
    [     'dec128' => new MongoDB\BSON\Decimal128('1234.5678') ],
    [     'binary' => new MongoDB\BSON\Binary('foo', MongoDB\BSON\Binary::TYPE_GENERIC) ],
    [     'date' => new MongoDB\BSON\UTCDateTime(1445990400000) ],
    [     'timestamp' => new MongoDB\BSON\Timestamp(1234, 5678) ],
    [     'regex' => new MongoDB\BSON\Regex('pattern', 'i') ],
    [     'code' => new MongoDB\BSON\Javascript('function() { return 1; }') ],
    [     'code_ws' => new MongoDB\BSON\Javascript('function() { return a; }', ['a' => 1]) ],
    [     'minkey' => new MongoDB\BSON\MinKey ],
    [     'maxkey' => new MongoDB\BSON\MaxKey ],
    ];

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

    ?>

    L'exemple ci-dessus va afficher :

    { "null" : null }
{ "boolean" : true }
{ "string" : "foo" }
{ "int32" : { "$numberInt" : "123" } }
{ "int64" : { "$numberLong" : "4294967295"} }
{ "double" : { "$numberDouble" : "1.0" } }
{ "nan" : { "$numberDouble" : "NaN" } }
{ "pos_inf" : { "$numberDouble" : "Infinity" } }
{ "neg_inf" : { "$numberDouble" : "-Infinity" } }
{ "array" : [ "foo", "bar" ] }
{ "document" : { "foo" : "bar" } }
{ "oid" : { "$oid" : "56315a7c6118fd1b920270b1" } }
{ "dec128" : { "$numberDecimal" : "1234.5678" } }
{ "binary" : { "$binary" : { "base64": "Zm9v", "subType" : "00" } } }
{ "date" : { "$date" : { "$numberLong" : "1445990400000" } } }
{ "timestamp" : { "$timestamp" : { "t" : 5678, "i" : 1234 } } }
{ "regex" : { "$regularExpression" : { "pattern" : "pattern", "options" : "i" } } }
{ "code" : { "$code" : "function() { return 1; }" } }
{ "code_ws" : { "$code" : "function() { return a; }", "$scope" : { "a" : { "$numberInt" : "1" } } } }
{ "minkey" : { "$minKey" : 1 } }
{ "maxkey" : { "$maxKey" : 1 } }
