MongoDB\BSON\toPHP
(mongodb >=1.0.0)
MongoDB\BSON\toPHP — Returns the PHP representation of a BSON value
Description
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.
Errors/Exceptions
- Throws MongoDB\Driver\Exception\InvalidArgumentException if a class in the type map cannot be instantiated or does not implement MongoDB\BSON\Unserializable.
- Throws MongoDB\Driver\Exception\UnexpectedValueException if the input did not contain exactly one BSON document. Possible reasons include, but are not limited to, invalid BSON, extra data (after reading one BSON document), or an unexpected » libbson error.
Changelog
| Version | Description |
|---|---|
| 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. |
| 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). |
| 1.3.0 |
MongoDB\Driver\Exception\UnexpectedValueException is thrown if the input contains an unsupported, deprecated BSON type. Previously, such types were ignored. |
Examples
Example #1 MongoDB\BSON\toPHP() example
<?php
$bson = hex2bin('0e00000010666f6f000100000000');
$value = MongoDB\BSON\toPHP($bson);
var_dump($value);
?>
The above example will output:
object(stdClass)#1 (1) {
["foo"]=>
int(1)
}
