An array of attributes that are passed to Router::url(). They typically look like:
array('controller' => 'posts', 'action' => 'view', 5)
An array of key => values that are composed into html attributes. For example:
<?php
// Given
array('class' => 'my-class', '_target' => 'blank')
// Would generate
class="my-class" _target="blank"
If an option can be minimized or accepts it’s name as the value, then true can be used:
<?php
// Given
array('checked' => true)
// Would generate
checked="checked"
Dot notation defines an array path, by separating nested levels with . For example:
Asset.filter.css
Would point to the following value:
array(
'Asset' => array(
'filter' => array(
'css' => 'got me'
)
)
)
