Answer 1

$tmp->parse("data1","sample_style",true);   
$tmp->parse("data1","sample_value",true);  改成一句：$tmp->parse("data1","sample",true);  

Answer 2

<select name="select" class="box" id="sample_style">
                <!-- BEGIN sample -->   <!--这里的空格只能是一个-->
                <option value="{sample_value}"> {sample_style}</option>
                <!-- END sample -->    <!--这里的空格只能是一个--> </select>$tmp->set_file("hd","NewSampleRegister.htm");
$tmp->set_block("hd","sample","data1");
for($i=0;$i<10;$i++){$tmp->set_var("sample_style",$i);
$tmp->set_var("sample_value",$i);
$tmp->parse("data1","sample",true);  
}
$tmp->parse("out","hd");
$tmp->p("out");

Answer 3

template.inc中：
  /* public: set_block(string $parent, string $handle, string $name = "")
   * extract the template $handle from $parent, 
   * place variable {$name} instead.
   */
  function set_block($parent, $handle, $name = "") {
    if (!$this->loadfile($parent)) {
      $this->halt("subst: unable to load $parent.");
      return false;
    }
    if ($name == "")
      $name = $handle;    $str = $this->get_var($parent);
    $reg = "/<!--\s+BEGIN $handle\s+-->(.*)\n\s*<!--\s+END $handle\s+-->/sm";
    preg_match_all($reg, $str, $m);
    $str = preg_replace($reg, "{" . "$name}", $str);
    $this->set_var($handle, $m[1][0]);
    $this->set_var($parent, $str);
  }
看这句：$reg = "/<!--\s+BEGIN $handle\s+-->(.*)\n\s*<!--\s+END $handle\s+-->/sm";  \s+至少一个空格
