Where he says:
==================================
I've been asked how to get the try MySQL type of fields, presumably so
folks could get the values of sets and enums. 

This is what I use (slightly modified): 

Function makeSelectList($table,$field){ 
   $s=""; 
   $rid=mysql_query("SHOW COLUMNS FROM $table"); 
   $nr=mysql_num_rows($rid); 

   while(list($name, $type)=mysql_fetch_row($rid)){ 
      if($name==$field){ 
         if(ereg('^enum\(.*\)$',$type)) 
            $type=substr($type,6,-2); 
         else if(ereg('^set\(.*\)$',$type)) 
                 $type=substr($type,5,-2); 
              else 
                 return("<option>ERROR"); 
         $opts=explode("','",$type); 
         while(list($k,$v)=each($opts)) 
            $s.="<option>$v"; 
      } 
   } 
   return($s); 
} 

Use the function as follows: 
echo
"<form><select name=\"selectfield\">".makeSelectList('tablename',
'field name').
"</select><input type=\"submit\"></form>"; type=\"submit\"></form>";
==================================
