What potential pitfalls should be considered when using nested arrays in PHP for organizing data?

One potential pitfall when using nested arrays in PHP for organizing data is the increased complexity in accessing and manipulating the data. This can lead to code that is harder to read and maintain. To address this, consider using associative arrays with meaningful keys to improve readability and make it easier to access specific elements within the nested arrays. 

// Example of using associative arrays to organize nested data
$data = [
    'user1' => [
        'name' => 'John Doe',
        'email' => 'john@example.com',
        'age' => 30
    ],
    'user2' => [
        'name' => 'Jane Smith',
        'email' => 'jane@example.com',
        'age' => 25
    ]
];

// Accessing data for user1
echo $data['user1']['name']; // Output: John Doe
echo $data['user1']['email']; // Output: john@example.com
echo $data['user1']['age']; // Output: 30
