What is the best approach to access an array within another array in PHP?

To access an array within another array in PHP, you can use multiple square brackets to navigate through the nested arrays. Each set of square brackets represents a level of nesting within the arrays. For example, if you have an array $outerArray containing another array $innerArray, you can access an element within $innerArray by using $outerArray['key']['nested_key']. 

$outerArray = array(
    'key' => array(
        'nested_key' => 'value'
    )
);

$value = $outerArray['key']['nested_key'];
echo $value; // Output: value
