(mongodb >=1.0.0)

MongoDB\Driver\Cursor::toArray — Returns an array containing all results for this cursor

说明

final public array MongoDB\Driver\Cursor::toArray ( void )

Iterates the cursor and returns its results in an array. MongoDB\Driver\Cursor::setTypeMap() may be used to control how documents are unserialized into PHP values.

参数

此函数没有参数。

返回值

Returns an array containing all results for this cursor.

错误／异常

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.

范例

Example #1 MongoDB\Driver\Cursor::toArray() example

  <?php

$manager  = new  MongoDB \ Driver \ Manager ( "mongodb://localhost:27017" );

 $bulk  = new  MongoDB \ Driver \ BulkWrite ;
 $bulk -> insert ([ 'x'  =>  1 ]);
 $bulk -> insert ([ 'x'  =>  2 ]);
 $bulk -> insert ([ 'x'  =>  3 ]);
 $manager -> executeBulkWrite ( 'db.collection' ,  $bulk );

 $query  = new  MongoDB \ Driver \ Query ([]);
 $cursor  =  $manager -> executeQuery ( 'db.collection' ,  $query );

 var_dump ( $cursor -> toArray ());

 ?>

以上例程的输出类似于：

array(3) {
  [0]=>
  object(stdClass)#6 (2) {
    ["_id"]=>
    object(MongoDB\BSON\ObjectID)#5 (1) {
      ["oid"]=>
      string(24) "564259a96118fd40b41bcf61"
    }
    ["x"]=>
    int(1)
  }
  [1]=>
  object(stdClass)#8 (2) {
    ["_id"]=>
    object(MongoDB\BSON\ObjectID)#7 (1) {
      ["oid"]=>
      string(24) "564259a96118fd40b41bcf62"
    }
    ["x"]=>
    int(2)
  }
  [2]=>
  object(stdClass)#10 (2) {
    ["_id"]=>
    object(MongoDB\BSON\ObjectID)#9 (1) {
      ["oid"]=>
      string(24) "564259a96118fd40b41bcf63"
    }
    ["x"]=>
    int(3)
  }
}
