What are the potential risks of dynamically changing variables in PHP code at runtime?

Changing variables dynamically at runtime in PHP can introduce potential risks such as making the code harder to debug, maintain, and understand. It can also lead to unexpected behavior and security vulnerabilities if not properly handled. To mitigate these risks, it is recommended to avoid dynamically changing variables whenever possible and instead use more structured and predictable programming patterns. 

// Avoid dynamically changing variables at runtime
$variable1 = 'value1';
$variable2 = 'value2';

// Instead, use a more structured approach
$data = [
    'variable1' => 'value1',
    'variable2' => 'value2'
];

// Access the values using keys
echo $data['variable1']; // Output: value1
echo $data['variable2']; // Output: value2
