  1696  * For encoding the html or the $encode_html parameter, there are three possible

  1697  * values. '0' will make urls footnotes and use make_url_footnote(). '1' will

  1698  * encode special characters and automatically display all of the content. The

  1699  * value of '2' will strip all HTML tags from the content.

  1700  *

  1701  * Also note that you cannot set the amount of words and not set the html

  1702  * encoding. If that is the case, then the html encoding will default to 2,

  1703  * which will strip all HTML tags.

  1704  *

  1705  * To restrict the amount of words of the content, you can use the cut

  1706  * parameter. If the content is less than the amount, then there won't be any

  1707  * dots added to the end. If there is content left over, then dots will be added

  1708  * and the rest of the content will be removed.
