What are the potential pitfalls of parsing and displaying nested arrays in PHP, as seen in the provided code snippet?

When parsing and displaying nested arrays in PHP, the potential pitfall is that the code may become complex and difficult to read, especially when dealing with multiple levels of nesting. To solve this issue and make the code more manageable, you can use recursive functions to iterate through the nested arrays and display the data in a structured manner. 

function displayNestedArray($array, $indent = 0) {
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            echo str_repeat("\t", $indent) . $key . ":\n";
            displayNestedArray($value, $indent + 1);
        } else {
            echo str_repeat("\t", $indent) . $key . ": " . $value . "\n";
        }
    }
}

$array = [
    'name' => 'John',
    'age' => 30,
    'address' => [
        'street' => '123 Main St',
        'city' => 'New York',
        'zipcode' => '10001'
    ]
];

displayNestedArray($array);
