PHP Revision::getTextId方法代码示例

 /**
  * Page moving and page protection (and possibly other things) creates null
  * revisions. These revisions re-use the previous text already stored in
  * the database. Those however do not trigger re-parsing of the page and
  * thus the ready tag is not updated. This watches for new revisions,
  * checks if they reuse existing text, checks whether the parent version
  * is the latest version and has a ready tag. If that is the case,
  * also adds a ready tag for the new revision (which is safe, because
  * the text hasn't changed). The interface will say that there has been
  * a change, but shows no change in the content. This lets the user to
  * update the translation pages in the case, the non-text changes affect
  * the rendering of translation pages. I'm not aware of any such cases
  * at the moment.
  * Hook: RevisionInsertComplete
  * @since 2012-05-08
