Example #1 mysql_xdevapi\CollectionAdd::__construct() 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 = $schema->getCollection("people");// Add two documents$collection ->add('{"name": "Fred", "age": 21, "job": "Construction"}') ->execute();$collection ->add('{"name": "Wilma", "age": 23, "job": "Teacher"}') ->execute();// Add two documents using a single JSON object$result = $collection ->add( '{"name": "Bernie", "jobs": [{"title":"Cat Herder","Salary":42000}, {"title":"Father","Salary":0}], "hobbies": ["Sports","Making cupcakes"]}', '{"name": "Jane", "jobs": [{"title":"Scientist","Salary":18000}, {"title":"Mother","Salary":0}], "hobbies": ["Walking","Making pies"]}') ->execute();// Fetch a list of generated ID's from the last add()$ids = $result->getGeneratedIds();print_r($ids);?>
The above example will output something similar to:
Array ( [0] => 00005b6b53610000000000000056 [1] => 00005b6b53610000000000000057 )
Note:
A unique _id is generated by MySQL Server 8.0 or higher, as demonstrated in the example. The _id field must be manually defined if using MySQL Server 5.7.
