Question

我希望动态写入关键字和描述元标记。我看到了这个thead，但我不能对元标记做同样的事情。
这是我的代码：http://runnable.com/VCSYsvEy0xov2fNi/my-for-php

的index.php

<?php
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<head>
<title><!--TITLE--></title>
    <meta http-equiv="Content-Language" content="it" />
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />  
    <meta name="keywords" content="<!--KEYWORDS-->" />
    <link rel="stylesheet" type="text/css" href="template/style.css">

    <script language="JavaScript">
        $(document).ready(function() {
            $(".topnav").accordion({
            accordion:false,
            speed: 500,
            closedSign: '[+]',
            openedSign: '[-]'
            });
        });
    </script>
</head>
<body>
        <div id="container">
            <div id="banner"><?php include('template/banner.php') ?></div>
            <!--<div id="nav_main"><?php include('template/nav_main.php') ?></div> -->
            <div id="navigation_left"><?php include("template/link_left.php") ?></div>      
            <div id="navigation_right" align="left"><?php include("template/link_right.php") ?></div>                               
            <div id="content"><?php include("$page.php") ?> </div>
            <div id="footer"><?php include('template/footer.php') ?></div>
        </div>
</body>
</html>
<?php
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
$pageKeywords = ob_get_contents();
ob_end_clean (); // Wipe the buffer

// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
echo str_replace ('<!--KEYWORDS-->', $pageKey, $pageKeywords);

?>

home.php（主页）

<?php $pageTitle = 'Full Metal Panic Italy | Home';?>
<?php $pageKey = 'full, metal, panic, fmp, fumoffu, the second raid, spoiler, mithril, amalgam, sigma';?>
<p style="background:#aaf">
  Lorem ipsum dolor sit amet, consectetaur adipisicing elit, sed do eiusmod tempor

</p>

标题可行，但不适用于元我究竟做错了什么？

Answer 1

这样做

$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer

// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
$pageContents = str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
$pageContents = str_replace ('<!--DESCRIPTION-->', $pageDesc, $pageContents);
echo str_replace ('<!--KEYWORDS-->', $pageKey, $pageContents);
