我有一个短代码，我想用一种更好、更干净的方式来写：

function webhosting_products_shortcode( $atts, $content = null) {
    $content=\'<h2 class="heading_blue">Eburnie Hosting vous offre:</h2>\'
            . \'<div class="hostingbox"><dl>\'
            . \'<dt><a href="http://hosting.eburnienetwork.com/web-hosting/index.php">Hébergement Web</a></dt>\'
            . \'<dd class="img"><img src="img/gamlastan.jpg" width="80" height="80" alt="Gamla Stan" /></dd>\'
            . \'<dd>Hébergement Web</dd></dl>\'
            . \'<dl  class="alt"><dt><a href="http://hosting.eburnienetwork.com/web-hosting/email-hosting.php">Hébergement Email</a></dt>\'
            . \'<dd class="img"><img src="img/gamlastan.jpg" width="80" height="80" alt="Gamla Stan" /></dd>\'
            . \'<dd>Hébergement Email</dd></dl>\'
            . \'<dl><dt><a href="http://hosting.eburnienetwork.com/website-design/index.php">Conception de Sites</a></dt>\'
            . \'<dd class="img"><img src="img/gamlastan.jpg" width="80" height="80" alt="Gamla Stan" /></dd>\'
            . \'<dd>Conception de Sites</dd></dl>\'
            . \'<dl><dt><a href="http://hosting.eburnienetwork.com/digital-ssl-certificate/index.php">Certificat SSL</a></dt>\'
            . \'<dd class="img"><img src="img/gamlastan.jpg" width="80" height="80" alt="Gamla Stan" /></dd>\'
            . \'<dd>Certificat SSL</dd></dl>\'
            . \'<dl><dt><a href="http://hosting.eburnienetwork.com/reseller-hosting.php">Programme Revendeur</a></dt>\'
            . \'<dd class="img"><img src="img/gamlastan.jpg" width="80" height="80" alt="Gamla Stan" /></dd>\'
            . \'<dd>Programme Revendeur</dd>\'
            . \'</dl></div>\';

    return $content;       
}
add_shortcode(\'webhosting\', \'webhosting_products_shortcode\');

shortcode[网络托管]正在发挥作用，但我认为这不是实现它的正确方式。谢谢

function webhosting_products_shortcode( $atts, $content = null) {
    ob_start();
    include(\'shortcodecontent.php\');
    $shortcode = ob_get_clean();
    return $shortcode;
}
add_shortcode(\'webhosting\', \'webhosting_products_shortcode\');
