PHP模板/布局功能

Question

I have this function but it's not good. It's making it hard to debug my code:

fun... {
    eval('?>' . str_replace(
        '{yield}',
        file_get_contents('templates/' . $template . '.phtml'),
        file_get_contents('templates/layouts/' . $layout . '.phtml')
    ));
}

Please let me know of better replacements.

Thanks.

function render($template, $layout) {
    $cache = "wherever/you/put/the/cache/file/{$template}_{$layout}.phtml";

    if (!file_exists($cache)) {
        $template = file_get_contents('templates/' . $template. '.phtml');
        $layout = file_get_contents('templates/layouts/' . $layout . '.phtml');

        $output = str_replace('{yield}', $template , $layout);
        file_put_contents($cache, $output);
    } else {
        include($cache);
    }
}
