我在zend框架中使用佈局。就好像現在看起來很醜很多很多代碼一樣。我想參考下面的代碼知道。我有可能給它一個更清潔的方法。這是我的代碼。優化Zend佈局

我見過很多次了，大多數人都用一些輔助方法來清理佈局文件。從自己的Zend框架
<!DOCTYPE html
PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<?php echo $this->headTitle() ?>
<?php echo $this->headScript() ?>
<?php echo $this->headStyle() ?>
</head>
<body>
<?php echo $this->render('header.phtml') ?>
<div id="nav"><?php echo $this->placeholder('nav') ?></div>
<div id="content"><?php echo $this->layout()->content ?></div>
<?php echo $this->render('footer.phtml') ?>
</body>
</html>
的例子，他們使用了一些輔助方法，如
$this->docType()
$this->headTitle()
$this->headScript()
$this->headStyle()
這種方法看起來很多清潔我。因爲他們在相同的文件中沒有多說這些。我想知道那個輔助方法的確切目的是什麼？以及如何在我的佈局文件中使用它？
