CollectionModify::arrayAppend

(No version information available, might only be in Git)

CollectionModify::arrayAppendAppend element to an array field

Description

public mysql_xdevapi\CollectionModify mysql_xdevapi\CollectionModify::arrayAppend ( string $collection_field , string $expression_or_literal )

Add an element to a document's field, as multiple elements of a field are represented as an array. Unlike arrayInsert(), arrayAppend() always appends the new element at the end of the array, whereas arrayInsert() can define the location.

Parameters

collection_field

The identifier of the field where the new element is inserted.

expression_or_literal

The new element to insert at the end of the document field array.

Return Values

A CollectionModify object that can be used to execute the command, or to add additional operations.

Examples

Example #1 mysql_xdevapi\CollectionModify::arrayAppend() 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");

$result $collection
  
->add(
  
'{"name":   "Bernie",
    "traits": ["Friend", "Brother", "Human"]}'

  ->
execute();

$collection
  
->modify("name in ('Bernie', 'Jane')")
  ->
arrayAppend('traits''Happy')
  ->
execute();

$result $collection
  
->find()
  ->
execute();

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

The above example will output something similar to:

Array
(
    [0] => Array
        (
            [_id] => 00005b6b5361000000000000010c
            [name] => Bernie
            [traits] => Array
                (
                    [0] => Friend
                    [1] => Brother
                    [2] => Human
                    [3] => Happy
                )
        )
)
