MongoDB\BSON\toPHP
(mongodb >=1.0.0)
MongoDB\BSON\toPHP — Returns the PHP representation of a BSON value
Descrierea
$bson
, array $typeMap = array()
) : array|object
Unserializes a BSON document (i.e. binary string) to its PHP representation.
The typeMap paramater may be used to control the PHP
types used for converting BSON arrays and documents (both root and embedded).
Fields containing deprecated BSON types (i.e. undefined, symbol, DBPointer) are represented only by bare-bones objects of the classes MongoDB\BSON\Undefined, MongoDB\BSON\Symbol, and MongoDB\BSON\DBPointer, when converting BSON to PHP. These objects are created from BSON data and used for storing these types back into the database, but can not be instantiated as they have a private constructor.
Parametri
-
bson(string) -
BSON value to be unserialized.
-
typeMap(array)
Valorile întoarse
The unserialized PHP value.
Erori/Excepții
- Throws MongoDB\Driver\Exception\InvalidArgumentException if a class in the type map cannot be instantiated or does not implement MongoDB\BSON\Unserializable.
- Emite MongoDB\Driver\Exception\UnexpectedValueException dacă la intrare nu se conține exact un document BSON. Motive posibile pentru aceasta sunt, dar nu se limitează la, BSON nevalid, date în plus (după citirea unui document BSON), sau o eroare neașteptată » libbson.
Istoricul schimbărilor
| Versiune | Descriere |
|---|---|
| PECL mongodb 1.4.0 |
If the input contains an unsupported, deprecated BSON type, the driver will now no longer log a warning to the debug log, but instead will create an object representing this type. |
| PECL mongodb 1.3.2 |
MongoDB\Driver\Exception\UnexpectedValueException is no longer thrown if the input contains an unsupported, deprecated BSON type. Such types will be ignored (as they were in versions before 1.3.0), although the driver will now log a warning to the debug log (see: mongodb.debug). |
| PECL mongodb 1.3.0 |
MongoDB\Driver\Exception\UnexpectedValueException is thrown if the input contains an unsupported, deprecated BSON type. Previously, such types were ignored. |
Exemple
Example #1 MongoDB\BSON\toPHP() example
<?php
$bson = hex2bin('0e00000010666f6f000100000000');
$value = MongoDB\BSON\toPHP($bson);
var_dump($value);
?>
Exemplul de mai sus va afișa:
object(stdClass)#1 (1) {
["foo"]=>
int(1)
}
