在zend Framework 1中处理layout.phtml
[英]deal with layout.phtml in zend framework 1
问题描述
I am following this tutorial(Getting Started with Zend Framework 1.11): http://akrabat.com/wp-content/uploads/Getting-Started-with-Zend-Framework.pdf 
我正在关注本教程（Zend Framework 1.11入门）： http : //akrabat.com/wp-content/uploads/Getting-Started-with-Zend-Framework.pdf
on page 10,zf-tutorial/application/layouts/scripts/layout.phtml, the code changed from: 在第10页，zf-tutorial / application / layouts / scripts / layout.phtml上，代码已更改为：
<?php echo $this->layout()->content; ?>
to: 至：
<?php
$this->headMeta()->appendHttpEquiv('Content-Type', 'text/html;charset=utf-8');
$this->headTitle()->setSeparator(' - ');
$this->headTitle('Zend Framework Tutorial');
echo $this->doctype(); ?>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<?php echo $this->headMeta(); ?>
<?php echo $this->headTitle(); ?>
</head>
<body>
<div id="content">
<h1><?php echo $this->escape($this->title); ?></h1>
<?php echo $this->layout()->content; ?>
</div>
</body>
Question: 题：
the output is the same, why need to change the code?
输出是一样的，为什么需要更改代码？ after I run the original code:
<?php echo $this->layout()->content; ?>在运行原始代码后： <?php echo $this->layout()->content; ?><?php echo $this->layout()->content; ?>, in page source code: there is such output:<!DOCTYPE HTML PUBLIC....after I run the modified code, in page source code,<!DOCTYPE HTML PUBLIC....supposed to appear twice, one from$this->headMeta()..., one from<?php echo $this->layout()->content; ?><?php echo $this->layout()->content; ?>，在页面源代码中：有这样的输出：<!DOCTYPE HTML PUBLIC....在运行修改后的代码后，在页面源代码中，<!DOCTYPE HTML PUBLIC....应该出现两次，其中之一$this->headMeta()...，其中一个来自<?php echo $this->layout()->content; ?><?php echo $this->layout()->content; ?>, but it only appears one time, why?<?php echo $this->layout()->content; ?>，但是只出现一次，为什么？

On page 10 you have the answer to your question: 在第10页上，您可以找到问题的答案：
Common HTML code: Layouts
It also very quickly becomes obvious that there will be a lot of common HTML code in our views for the header and footer sections at least and maybe a side bar or two also.
If you're getting duplicated results you must be including all those common header definition in both view and layout . 如果要得到重复的结果，则必须在视图和布局中都包含所有这些通用的标头定义。 Make sure to remove them from your views . 确保从视图中删除它们。
