Example #1 A DocResult example

$session 
mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();

$schema $session->getSchema("addressbook");
$create $schema->createCollection("people");

$create->add('{"name": "Alfred", "age": 18, "job": "Butler"}')->execute();
$create->add('{"name": "Reginald", "age": 42, "job": "Butler"}')->execute();

// ...

$collection $schema->getCollection("people");

// Yields a DocResult object
$result $collection
  
->find('job like :job and age > :age')
  ->
bind(['job' => 'Butler''age' => 16])
  ->
sort('age desc')
  ->
limit(1)
  ->
execute();

var_dump($result->fetchAll());
?>

以上例程的输出类似于:

array(1) {
  [0]=>
  array(4) {
    ["_id"]=>
    string(28) "00005b6b536100000000000000f3"
    ["age"]=>
    int(42)
    ["job"]=>
    string(6) "Butler"
    ["name"]=>
    string(8) "Reginald"
  }
}
