What are the potential pitfalls of creating multidimensional arrays in PHP when dealing with database connections and data retrieval?

When creating multidimensional arrays in PHP for database connections and data retrieval, one potential pitfall is the increased complexity and potential for errors in managing the nested arrays. To avoid this, consider using associative arrays with meaningful keys to organize and access the data more easily. 

// Example of using associative arrays for database connections and data retrieval

// Database connection
$connection = [
    'host' => 'localhost',
    'username' => 'root',
    'password' => 'password',
    'database' => 'my_database'
];

// Data retrieval
$data = [
    [
        'id' => 1,
        'name' => 'John Doe',
        'email' => 'john.doe@example.com'
    ],
    [
        'id' => 2,
        'name' => 'Jane Smith',
        'email' => 'jane.smith@example.com'
    ]
];

// Accessing data
echo $data[0]['name']; // Output: John Doe
