pager_default_initialize($total, $limit, $element = 0) Initializes a pager. This function sets up the necessary global variables so that the render system will correctly process #type 'pager' render arrays to output pagers that correspond to the items being displayed. If the items being displayed result from a database query performed using Drupal's database API, and if you have control over the construction of the database query, you do not need to call this function directly; instead, you can

public PagerSelectExtender::setCountQuery(SelectInterface $query) Specify the count query object to use for this pager. You will rarely need to specify a count query directly. If not specified, one is generated off of the pager query itself. Parameters \Drupal\Core\Database\Query\SelectInterface $query: The count query object. It must return a single row with a single column, which is the total number of records. File core/lib/Drupal/Core/Database/Query/PagerSelectExtender.php, line 107 Cla

public PagerSelectExtender::limit($limit = 10) Specify the maximum number of elements per page for this query. The default if not specified is 10 items per page. Parameters int|false $limit: An integer specifying the number of elements per page. If passed a false value (FALSE, 0, NULL), the pager is disabled.

protected PagerSelectExtender::ensureElement() Ensure that there is an element associated with this query.

public PagerSelectExtender::element($element) Specify the element ID for this pager query. The element is used to differentiate different pager queries on the same page so that they may be operated independently. If you do not specify an element, every pager query on the page will get a unique element. If for whatever reason you want to explicitly define an element for a given query, you may do so here. Setting the element here also increments the static $maxElement counter, which is used for d
