What are the potential pitfalls of using dynamic variables in PHP, as highlighted in the forum thread?

The potential pitfalls of using dynamic variables in PHP include security risks, readability issues, and potential conflicts with variable names. To avoid these pitfalls, it is recommended to use associative arrays instead of dynamic variables. 

// Using associative arrays instead of dynamic variables
$data = [
    'name' => 'John',
    'age' => 30,
    'email' => 'john@example.com'
];

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