PHP Scoped輸出緩衝區，如何？

如何堆棧輸出緩衝區，以便每個緩衝區都有自己的ID？PHP Scoped輸出緩衝區，如何？

所以，我有一個緩衝區的HTML頁面，但也有一個頁面內容連接a hook。鉤子本身也包含輸出緩衝：

<?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(); ?>

第一ob_get_clean()剛剛停止輸出緩衝區中的HTML頁面。

那麼，是否有可能有這樣的機制？

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

讓每個ob_get_clean()都會有自己的價值：

#template → <html> … </html>
#page → <p>Lorem ipsum dolor sit amet.</p>

我得到了這些錯誤：

我會盡量玩這個：http://php.net/manual/en/function.ob-get-level.php –

您需要的ob_get_clean值賦值給一個變量

<?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); ?>

請注意，我把引號$頁面級>內容，以方便閱讀這個代碼，你應該不要使用這些引號。

是的，我確實把輸出內容放在每次輸出變量緩衝區結束。這就是我使用輸出緩衝區的原因。但我不知道爲什麼有這個錯誤信息。 –

PHP Scoped輸出緩衝區，如何？
