PHP include 内部变量

Question

我有一个控制页面输出的函数:

$page = "<div class='media-title'><h2>{$title}</h2></div><div class='media-image'>{$image}</div><div class='media-desc'>{$desc}</div>";

我想在 $page 中定义的 html 中包含一个文件“box.php”多变的。我试过这个:

$page = "<div class='media-title'><h2>{$title}</h2></div><div class='media-image'>{$image}</div><div class="inlinebox">" . include("box.php"); . "</div><div class='media-desc'>{$desc}</div>";

...但是没有用。如何将 php include 放入变量中？

来自 php.net

// put this somewhere in your main file, outside the
// current function that contains $page
function get_include_contents($filename) {
    if (is_file($filename)) {
        ob_start();
        include $filename;
        $contents = ob_get_contents();
        ob_end_clean();
        return $contents;
    }
    return false;
}

// put this inside your current function
$string = get_include_contents('box.php');
$page  = '<div class="media-title"><h2>{$title}</h2></div>';
$page .= '<div class="media-image">{$image}</div>';
$page .= '<div class="inlinebox">' . $string . '</div>';
$page .= '<div class="media-desc">{$desc}</div>';
