Php tags in .html files don't work in WebMatrix

问题

I've been learning web development and the book I am learning from is using php tags within html files but they don't work for me, here is my header page:

<!DOCTYPE html>

<html lang="en">
<head>
    <meta http-equiv="content-type" content="text/html; charset=iso-8859-1" />
    <title><?php echo $page_title; ?></title>
    <style type="text/css" media="all">@import "./includes/layout.css";</style>
</head>
<body>
    <a href="index.php" class="logo"> <img src="Includes/Images/NameIconSplash.png" /></a>
    <div id="wrapper">
        <div id="content">
            <div id="news">
                <div id="nav">
                    <ul>
                        // Tags don't work here
                        <?php
                            if ( (isset($_COOKIE['user_id'])) && (!strpos($_SERVER['PHP_SELF'], 'logout.php')) ) 
                            {
                                echo '<li><a href="logout.php">                                           Logout</a></li>'
                            } 
                            else 
                            {
                                echo '<li><a href="login.php">                                            Login</a></li>'
                                echo '<li><a href="register.php">                                         Register</a></li>'
                            }
                        ?>




                    </ul>
                </div>

The php code is just normal black text but it recognises the html code within the php tags. Does someone know why it doesn't recognise them?

Thankyou in advance.

Please change file extention from .html to .php

回答2:

Web servers are configured to detect the file type by looking at the extension. By default it will route .php files through the PHP interpreter, and .html files will be served directly to the end user. You can configure this behaviour via the server's config file, or the local .htaccess file for the individual web directory.

RemoveHandler .html .htm
AddType application/x-httpd-php .php .htm .html

Do this if you really don't want to save your files as .php. Or else saving your files with .php does the job

If you want to use php code you have to use .php extension, so change extension to .php.
