MongoDB\Driver\Cursor::toArray
(mongodb >=1.0.0)
MongoDB\Driver\Cursor::toArray — Returns an array containing all results for this cursor
说明
final public MongoDB\Driver\Cursor::toArray(): array
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
示例 #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)
}
}
