User

User interface describes a single user:

1. ID (if available),
2. First name,
3. Last name,
4. Email address.

First and last name can be parsed from full name, or full name can be assembled from first and last name, depending on strategy that you select for implementation.

Identified and Unidentified Visitors

This library offers two solid classes: ActiveCollab\User\UnidentifiedVisitor is a visitor that we know nothing about, and ActiveCollab\User\IdentifiedVisitor which describe a single user who announces their identity by providing their email address and optionally full name.

$user = new ActiveCollab\User\IdentifiedVisitor('Ilija Studen', '[email protected]');

print $user->getFirstName() . "\n";
print $user->getLastName() . "\n";
print $user->formatName(ActiveCollab\User\UserInterface::NAME_INITIALS) . "\n";

Users with Accounts

If the app has a concept of users with accounts, these classes should implement ActiveCollab\User\UserInterface and provide access to required properties:

1. User ID,
2. User's email address,
3. User's first and last name or full name.

Depending on what you have stored for #3, you can use one of the two traits to get most of the UserInterface implementation pasted to your user classes:

1. ActiveCollab\User\UserInterface\ImplementationUsingFirstAndLastName
2. ActiveCollab\User\UserInterface\ImplementationUsingFullName

Serialization

All instances that implement ActiveCollab\User\UserInterface can be serialized to JSON:

$user = new ActiveCollab\User\IdentifiedVisitor('Ilija Studen', '[email protected]');
print_r(json_decode(json_encode($user), true));

will output:

(
    [id] => 0
    [class] => ActiveCollab\User\IdentifiedVisitor
    [first_name] => Ilija
    [last_name] => Studen
    [full_name] => Ilija Studen
    [email] => [email protected]
)

Comparing Users

UserInterface::is() method is handy when you need to check if a particular user instance is the same person as another instance:

$user1 = new ActiveCollab\User\IdentifiedVisitor('John Doe', '[email protected]');
$user2 = new ActiveCollab\User\IdentifiedVisitor('Jane Doe', '[email protected]');

if ($user1->is($user2)) {
    print "Same person\n";
} else {
    print "Not the same person\n";
}

Users with accounts (ID > 0) are compared by their ID, and visitors without an account are compared by their email address. Comparisons are not mixed, so user with account will never be identified as visitor, even when their email addresses match.
