What are best practices for navigating nested arrays in PHP?

When navigating nested arrays in PHP, it is important to use recursive functions to efficiently access and manipulate the data within the arrays. By using a recursive function, you can iterate through each level of the nested arrays and handle the data accordingly. This approach allows for flexibility and scalability when working with complex nested structures. 

function navigateNestedArray($array) {
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            navigateNestedArray($value);
        } else {
            // Perform operations on the leaf nodes of the array
            echo $key . ': ' . $value . PHP_EOL;
        }
    }
}

// Example usage
$array = [
    'key1' => 'value1',
    'key2' => [
        'subkey1' => 'subvalue1',
        'subkey2' => 'subvalue2'
    ],
    'key3' => 'value3'
];

navigateNestedArray($array);
