范例

Example #1 CollectionFind example


<?php
$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();

// ...

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

$result = $collection
  ->find('job like :job and age > :age')
  ->bind(['job' => 'Butler', 'age' => 16])
  ->execute();

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

以上例程的输出类似于：

array(1) {
  [0]=>
  array(4) {
    ["_id"]=>
    string(28) "00005b6b536100000000000000cf"
    ["age"]=>
    int(18)
    ["job"]=>
    string(6) "Butler"
    ["name"]=>
    string(6) "Alfred"
  }
}
