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.

参数

bson (string)

BSON value to be unserialized.

typeMap (array)

Type map configuration.

返回值

The unserialized PHP value.

更新日志

版本 说明
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.

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)
}
