What is the purpose of using an Enumeration class in PHP and what potential benefits does it offer in terms of code organization and readability?

Using an Enumeration class in PHP allows developers to define a set of named constants that represent a fixed number of possible values. This helps in improving code organization by centralizing all related constants in one class. Additionally, it enhances code readability as it provides meaningful names for each constant value, making the code more understandable and maintainable. 

class StatusEnum {
    const PENDING = 'pending';
    const APPROVED = 'approved';
    const REJECTED = 'rejected';
}

// Usage example
$status = StatusEnum::PENDING;
if ($status === StatusEnum::APPROVED) {
    echo 'The status is approved.';
}
