What are the potential pitfalls of working with data based on positions in PHP?

When working with data based on positions in PHP arrays, one potential pitfall is that the positions may change if the array is modified. To avoid this issue, it is recommended to use associative arrays with keys that are more stable identifiers for the data. 

// Example of using associative arrays instead of position-based arrays
$data = array(
    'id' => 1,
    'name' => 'John Doe',
    'email' => 'johndoe@example.com'
);

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