   3  The LinkCache class maintains a list of article titles and the information about
   4  whether or not the article exists in the database. This is used to mark up links
   5  when displaying a page. If the same link appears more than once on any page,
   6  then it only has to be looked up once. In most cases, link lookups are done in
   7  batches with the LinkBatch class, or the equivalent in Parser::replaceLinkHolders(),
   8  so the link cache is mostly useful for short snippets of parsed text (such as
   9  the site notice), and for links in the navigation areas of the skin.
  10  
  11  The link cache was formerly used to track links used in a document for the
  12  purposes of updating the link tables. This application is now deprecated.

  14  To create a batch, you can use the following code:
  15  
  16  $pages = array( 'Main Page', 'Project:Help', /* ... */ );
  17  $titles = array();
  18  
  19  foreach( $pages as $page ){
  20      $titles[] = Title::newFromText( $page );
  21  }
  22  
  23  $batch = new LinkBatch( $titles );
  24  $batch->execute();
