如何堆叠输出缓冲区，使每个缓冲区都有自己的ID

因此，我有一个带有缓冲区的HTML页面，但也有一个与缓冲区连接的页面内容。挂钩本身还包含输出缓冲区：

<?php ob_start(); ?>
<html>
  <head></head>
  <body>
    <?php ob_start(); ?>
    <?php echo $page->content; ?>
    <?php echo ob_get_clean(); ?>
  </body>
</html>
<?php ob_get_clean(); ?>

因此，每个

ob\u get\u clean（）

都有自己的值：

```
#模板
```
→ <代码>…
```
#第页
```
→ <代码>Lorem ipsum dolor sit amet.

我犯了以下错误：

谢谢。

您需要为变量赋值ob\u get\u clean

<?php ob_start(); ?>
<html>
  <head></head>
  <body>
    <?php ob_start(); ?>
    <?php echo '$page->content'; ?>
    <?php $inner = ob_get_clean(); ?>
  </body>
</html>
<?php $outer = ob_get_clean(); ?>
<?php var_dump($inner, $outer); ?>

请注意，我在$page->content周围加了引号，为了便于阅读此代码，您不应该使用这些引号。

是的，我确实在每次输出缓冲区结束时都将输出内容放在变量上。这就是为什么我使用输出缓冲区。但我不知道为什么会出现这样的错误消息。我将尝试处理以下问题：

<?php ob_start(); ?>
<html>
  <head></head>
  <body>
    <?php ob_start(); ?>
    <?php echo '$page->content'; ?>
    <?php $inner = ob_get_clean(); ?>
  </body>
</html>
<?php $outer = ob_get_clean(); ?>
<?php var_dump($inner, $outer); ?>
