composer require josantonius/session --prefer-source

You can also clone the complete repository with Git:

git clone https://github.com/josantonius/php-session.git

Available Classes

Session Class

Josantonius\Session\Session

Starts the session:

/**
 * @throws HeadersSentException        if headers already sent.
 * @throws SessionStartedException     if session already started.
 * @throws WrongSessionOptionException if setting options failed.
 * 
 * @see https://php.net/session.configuration for List of available $options.
 */
public function start(array $options = []): bool;

Check if the session is started:

public function isStarted(): bool;

Sets an attribute by name:

/**
 * @throws SessionNotStartedException if session was not started.
 */
public function set(string $name, mixed $value): void;

Gets an attribute by name:

/**
 * Optionally defines a default value when the attribute does not exist.
 */
public function get(string $name, mixed $default = null): mixed;

Gets all attributes:

public function all(): array;

Check if an attribute exists in the session:

public function has(string $name): bool;

Sets several attributes at once:

/**
 * If attributes exist they are replaced, if they do not exist they are created.
 * 
 * @throws SessionNotStartedException if session was not started.
 */
public function replace(array $data): void;

Deletes an attribute by name and returns its value:

/**
 * Optionally defines a default value when the attribute does not exist.
 * 
 * @throws SessionNotStartedException if session was not started.
 */
public function pull(string $name, mixed $default = null): mixed;

Deletes an attribute by name:

/**
 * @throws SessionNotStartedException if session was not started.
 */
public function remove(string $name): void;

Free all session variables:

/**
 * @throws SessionNotStartedException if session was not started.
 */
public function clear(): void;

Gets the session ID:

public function getId(): string;

Sets the session ID:

/**
 * @throws SessionStartedException if session already started.
 */
public function setId(string $sessionId): void;

Update the current session ID with a newly generated one:

/**
 * @throws SessionNotStartedException if session was not started.
 */
public function regenerateId(bool $deleteOldSession = false): bool;

Gets the session name:

public function getName(): string;

Sets the session name:

/**
 * @throws SessionStartedException if session already started.
 */
public function setName(string $name): void;

Destroys the session:

/**
 * @throws SessionNotStartedException if session was not started.
 */
public function destroy(): bool;

Session Facade

Josantonius\Session\Facades\Session

 * @throws WrongSessionOptionException if setting options failed.
 * 
 * @see https://php.net/session.configuration for List of available $options.
