What are the potential pitfalls of using if statements to check license codes in PHP?

Potential pitfalls of using if statements to check license codes in PHP include the possibility of code duplication, making the code harder to maintain and prone to errors. Additionally, using if statements for each license code can lead to inefficient code execution if there are a large number of codes to check. To solve this issue, it is recommended to use a data structure like an associative array to store the license codes and their corresponding actions. 

$licenseCodes = [
    'CODE1' => 'Action1',
    'CODE2' => 'Action2',
    'CODE3' => 'Action3',
    // Add more license codes and actions as needed
];

$licenseCode = 'CODE2';

if (array_key_exists($licenseCode, $licenseCodes)) {
    $action = $licenseCodes[$licenseCode];
    // Perform the action based on the license code
    echo $action;
} else {
    // Handle invalid license code
    echo 'Invalid license code';
}
