我希望有人能帮助我。我如何通过扩展原始类来最好地动态更改页面标题、desc或key vs.vs？以下是我目前所拥有的：
<?php
class siteGlobal
{
public $arr = array('title'=>'Page Default title','desc'=>'Page default description');
public function pageHeader()
{ ?>
<!doctype html><html>
<?php }
public function metaTags()
{ ?>
<head>
<meta charset="utf-8">
<title><?php echo $this->arr['title'];?></title>
<meta name="description" content="<?php echo $this->arr['desc'];?>">
<?php }
public function pageBody()
{ ?>
</head>
<body>
<?php }
public function pageFooter()
{ ?>
</body>
</html>
<?php }
} ?>
其他页面
require_once('siteGlobal.php');
class pageDetail extends siteGlobal
{
public function __construct()
{
$this->pageHeader();
$this->newMetas();
$this->startBody();
$this->sayfaBilgileri();
$this->pageFooter();
}
public function newMetas()
{
parent::metaTags();
}
public function sayfaBilgileri()
{
//HOW I can write a new title and description in this function to siteGlobal.php (public $metaInfo) ?>
<div style="width:640px; margin:0 auto;">
<h1>Page New Title</h1>
<h2>Page New Subtitle</h2>
<p>Lorem Ipsum, bla bla....</p>
</div>
<?php }
}
$writePage = new pageDetail(); ?>
您可以尝试在父类中创建一个方法，比如：
protected function setTitle($title){
$this->arr['title'] = $title;
}
并以这种方式在扩展类中使用它：
parent::setTitle("My title");
