MongoDB\BSON\toPHP — Returns the PHP representation of a BSON value
说明
MongoDB\BSON\toPHP
( string $bson
[, array $typeMap = array()
] ) : array|object
Unserializes a BSON document (i.e. binary string) to its PHP representation.
The typeMap paramater may be used to control the PHP
types used for converting BSON arrays and documents (both root and embedded).
Warning Fields containing deprecated BSON types (i.e. undefined, symbol, DBPointer) are represented only by bare-bones objects of the classes MongoDB\BSON\Undefined, MongoDB\BSON\Symbol, and MongoDB\BSON\DBPointer, when converting BSON to PHP. These objects are created from BSON data and used for storing these types back into the database, but can not be instantiated as they have a private constructor.
返回值
The unserialized PHP value.
错误／异常
- Throws MongoDB\Driver\Exception\InvalidArgumentException if a class in the type map cannot be instantiated or does not implement MongoDB\BSON\Unserializable.
- Throws MongoDB\Driver\Exception\UnexpectedValueException if the input did not contain exactly one BSON document. Possible reasons include, but are not limited to, invalid BSON, extra data (after reading one BSON document), or an unexpected » libbson error.
更新日志
| 版本 | 说明 |
|---|---|
| PECL mongodb 1.4.0 | If the input contains an unsupported, deprecated BSON type, the
driver will now no longer log a warning to the debug log, but instead will create an object representing this type. |
| PECL mongodb 1.3.2 | MongoDB\Driver\Exception\UnexpectedValueException
is no longer thrown if the input contains an unsupported, deprecated BSON type. Such types will be ignored (as they were in versions before 1.3.0), although the driver will now log a warning to the debug log (see: mongodb.debug). |
| PECL mongodb 1.3.0 | MongoDB\Driver\Exception\UnexpectedValueException
is thrown if the input contains an unsupported, deprecated BSON type. Previously, such types were ignored. |
范例
Example #1 MongoDB\BSON\toPHP() example
<?php$bson = hex2bin('0e00000010666f6f000100000000');$value = MongoDB\BSON\toPHP($bson);var_dump($value);?>
以上例程会输出：
object(stdClass)#1 (1) {
["foo"]=>
int(1)
}
