错误/异常

范例

示例 #1 MongoDB\Driver\WriteConcern::bsonSerialize() with majority write concern

<?php

$wc 
= new MongoDB\Driver\WriteConcern(MongoDB\Driver\WriteConcern::MAJORITY);
var_dump($wc->bsonSerialize());

echo 
"\n"MongoDB\BSON\toJSON(MongoDB\BSON\fromPHP($wc));

?>

以上例程的输出类似于:

object(stdClass)#2 (1) {
  ["w"]=>
  string(8) "majority"
}

{ "w" : "majority" }

示例 #2 MongoDB\Driver\WriteConcern::bsonSerialize() with wtimeout and journal

<?php

$wc 
= new MongoDB\Driver\WriteConcern(21000true);
var_dump($wc->bsonSerialize());

echo 
"\n"MongoDB\BSON\toJSON(MongoDB\BSON\fromPHP($wc));

?>

以上例程的输出类似于:

object(stdClass)#2 (3) {
  ["w"]=>
  int(2)
  ["j"]=>
  bool(true)
  ["wtimeout"]=>
  int(1000)
}

{ "w" : 2, "j" : true, "wtimeout" : 1000 }
