[thelist] Re: Variable Stylesheets

Mon Dec 3 06:22:56 CST 2001

This is a PHP script I use to generate conditional stylesheets & DTD
headers based on user agent. All you have to do is create specific
(external) stylesheets based on browsers.  This is setup for the 4 major
types:
IE/NN on Mac/Win platforms

Feel free to use and enjoy!

/* begin DTD header creation */

  function _brfind($component){
   global $HTTP_USER_AGENT;
   $result = stristr($HTTP_USER_AGENT,$component);
   return $result;
  }

  function get_doctype(){
   if ( $this->_brfind('MSIE 4') or $this->_brfind('MSIE 5') ) {
    if ( $this->_brfind('Mac') ) {
     $style = ( $this->_brfind('MSIE 5') ) ? '<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Transitional//EN"
"DTD/xhtml1-transitional.dtd">':'stylemac.css';
    } elseif ( $this->_brfind('Win') ) {
     $style = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0
Transitional//EN">';
    }
   } elseif ( !$this->_brfind('MSIE') ) {
    if ( $this->_brfind('Mozilla/5') or $this->_brfind('Mozilla/6') ) {
     $style = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01
Transitional//EN"
"http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">';
    } elseif ( $this->_brfind('Mozilla/4') ) {
     if ( $this->_brfind('Mac') ) {
      $style = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2
Final//EN">';
     } elseif ( $this->_brfind('Win') ) {
      $style = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01
Transitional//EN">';
     } else {
      $style = '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01
Transitional//EN">';
     }
    }
   }
   return $style;
  }
/*end DTD header creation */
