doctype - print DOCTYPE declaration


<doctype $langver [$type]>

The <doctype> function prints a <!DOCTYPE> declaration based on the $langver and $type arguments, which are shorthand aliases for some common delcarations.

  • html2.0 - For HTML 2.0

  • html4.01 - For HTML 4.01; a $type must be given also

  • xhtml1.0 - For XHTML 1.0; a $type must be given also

  • xhtml1.1 - For XHTML 1.1

The possible values for $type are:

  • strict - For the Strict DTD
