Are there any specific best practices for handling nested arrays in PHP?

When working with nested arrays in PHP, it is important to use recursive functions to properly handle the nested structure. This allows you to iterate through each level of the nested array and perform operations as needed. Additionally, using array functions like array_map or array_walk_recursive can simplify the process of working with nested arrays. 

function processNestedArray($nestedArray) {
    foreach ($nestedArray as $key => $value) {
        if (is_array($value)) {
            processNestedArray($value);
        } else {
            // Perform operations on the nested array values
            // For example, echo $value for demonstration purposes
            echo $value . "\n";
        }
    }
}

$nestedArray = [
    'key1' => 'value1',
    'key2' => [
        'nestedKey1' => 'nestedValue1',
        'nestedKey2' => 'nestedValue2'
    ]
];

processNestedArray($nestedArray);
