    How to Check if a Document Exists

    • To check whether the database contains a certain document,
      use the session.advanced operations exists method.

    • Calling exists does not load the document entity to the session, and the session will not track it.

    • In this page:

    Check if document exists 

    $exists = $session->advanced()->exists("employees/1-A");

if ($exists)
{
    // document 'employees/1-A exists
}

    Syntax 

    public function exists(?string $id): bool;
    Parameter Type Description
    $id ?string The ID of the document to look for
    Return Value Description
    bool true - this document exists in the database.
    false - The document does Not exist in the database
