SessionIdInterface
SessionIdInterface is an optional interface a session handler can implement to generate its own session IDs. It defines a single method create_sid(): string returning a new unique session identifier.
When PHP needs a new session ID and the handler implements this interface, create_sid() is called instead of the built-in ID generation.
<?php
class CustomSessionHandler implements SessionHandlerInterface, SessionIdInterface {
public function create_sid(): string {
return bin2hex(random_bytes(16));
}
// ... implement remaining SessionHandlerInterface methods
}
?>
