Example #1 mysql_xdevapi\Collection::count() 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");
$collection = $schema->getCollection("people");
$result = $collection
->add(
'{"name": "Bernie",
"jobs": [
{"title":"Cat Herder","Salary":42000},
{"title":"Father","Salary":0}
],
"hobbies": ["Sports","Making cupcakes"]}',
'{"name": "Jane",
"jobs": [
{"title":"Scientist","Salary":18000},
{"title":"Mother","Salary":0}
],
"hobbies": ["Walking","Making pies"]}')
->execute();
var_dump($collection->count());
?>
The above example will output:
int(2)
