Dot Notation¶

The dot notation refers to a syntax to access deeply-nested elements in arrays. Instead of repeating the classic [index] notation, dot notation offers a way to chain the indices with dots to reach the value.

Dot notation is easier to read, in particular when there are numerous elements.

Dot notation is not a PHP native feature. It is available via independent packages or as feature of frameworks.

<?php

// example from https://github.com/adbario/php-dot-notation

$array['info']['home']['address'] = 'Kings Square';

echo $array['info']['home']['address'];

// Kings Square

$dot->set('info.home.address', 'Kings Square');

echo $dot->get('info.home.address');

?>
