Example #1 mysql_xdevapi\Collection::find() 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 = $session->getSchema("addressbook");$collection = $schema->createCollection("people");$collection->add('{"name": "Alfred", "age": 18, "job": "Butler"}')->execute();$collection->add('{"name": "Bob", "age": 19, "job": "Swimmer"}')->execute();$collection->add('{"name": "Fred", "age": 20, "job": "Construction"}')->execute();$collection->add('{"name": "Wilma", "age": 21, "job": "Teacher"}')->execute();$collection->add('{"name": "Suki", "age": 22, "job": "Teacher"}')->execute();$find = $collection->find('job LIKE :job AND age > :age');$result = $find ->bind(['job' => 'Teacher', 'age' => 20]) ->sort('age DESC') ->limit(2) ->execute();print_r($result->fetchAll());?>
The above example will output:
Array ( [0] => Array ( [_id] => 00005b6b536100000000000000a8 [age] => 22 [job] => Teacher [name] => Suki ) [1] => Array ( [_id] => 00005b6b536100000000000000a7 [age] => 21 [job] => Teacher [name] => Wilma ) )
