In PHP development, what are some common pitfalls to avoid when structuring data arrays for efficient processing in controllers and models?

One common pitfall to avoid when structuring data arrays for efficient processing in controllers and models is nesting arrays too deeply. This can make it difficult to access and manipulate the data efficiently. To solve this issue, flatten the array structure by using associative keys to represent nested data. 

// Incorrect way of structuring data arrays
$data = [
    'users' => [
        'user1' => [
            'name' => 'John',
            'age' => 30
        ],
        'user2' => [
            'name' => 'Jane',
            'age' => 25
        ]
    ]
];

// Correct way of structuring data arrays
$data = [
    'users' => [
        'user1' => ['name' => 'John', 'age' => 30],
        'user2' => ['name' => 'Jane', 'age' => 25]
    ]
];
