PHP index.php包括结构[关闭]

I need help. On my site I use URL parameters to decide which other PHP files to include on the page. My first question is: What should be in index.php and what should be in the included PHP file?

On the Internet I found instructions, suggesting this structure for index.php:

<html>
    <head>
        <?php include 'header.php'; ?>
    </head>
    <body>
        <?php include 'menu.php'; ?>
        <?php include 'content.php'; /* Including page based on the parameters in the url */ ?>
    </body>
</html>

With this structure, how can I change the data in the <head> section based on the content in content.php? For example, for index.php?option=article&id_article=1, I will include article.php and show the article with id 1. How, then, can I change the <title>, <meta>, etc content when <head> was written before including the article?

Thanks!

    One option that is kind of ugly but will work is instead of having header.php echo have it simply set variables like $title and $meta[]. Also instead of having article.php from echoing return a variable like $html. Also in article.php you can then overwrite any of the variables set in header.php. Then you can construct your index.php like so:

    <?php include 'header.php'; ?>
<?php include 'article.php'; ?>
<html>
<head>
    <?php echo $title ?>
</ head>
<body>
<?php include 'menu.php'; ?>
<?php echo $html ?>
</ body>
</ html>

    Or you can look into ob_start() and ob_flush() etc...
