范例

Example #1 MongoDB\Driver\WriteException::getWriteResult() example

  <?php

$manager  = new  MongoDB \ Driver \ Manager ( 'mongodb://localhost' );
 $bulk  = new  MongoDB \ Driver \ BulkWrite ;
 $bulk -> insert ([ '_id'  =>  1 ]);
 $bulk -> insert ([ '_id'  =>  1 ]);

try {
     $manager -> executeBulkWrite ( 'db.collection' ,  $bulk );
} catch ( MongoDB \ Driver \ Exception \ WriteException $e ) {
     $writeResult  =  $e -> getWriteResult ();

    if ( $writeConcernError  =  $writeResult -> getWriteConcernError ()) {
         var_dump ( $writeConcernError );
    }

    if ( $writeErrors  =  $writeResult -> getWriteErrors ()) {
         var_dump ( $writeErrors );
    }
}

 ?>

以上例程的输出类似于：

array(1) {
  [0]=>
  object(MongoDB\Driver\WriteError)#5 (4) {
    ["message"]=>
    string(70) "E11000 duplicate key error index: db.collection.$_id_ dup key: { : 1 }"
    ["code"]=>
    int(11000)
    ["index"]=>
    int(1)
    ["info"]=>
    NULL
  }
}
