范例

Example #1 mysql_xdevapi\Schema::getCollections() 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");
$collect = $schema->createCollection("people");
$collect->add('{"name": "Fred",  "age": 21, "job": "Construction"}')->execute();
$collect->add('{"name": "Wilma", "age": 23, "job": "Teacher"}')->execute();

$collections = $schema->getCollections();
var_dump($collections);
?>

以上例程的输出类似于：

array(1) {
  ["people"]=>
  object(mysql_xdevapi\Collection)#4 (1) {
    ["name"]=>
    string(6) "people"
  }
}
