PHP Scoped输出缓冲区，如何？

分类: 技术问答 • 2022-08-05 10:45:29
问题描述：

如何堆栈输出缓冲区，以便每个缓冲区都有自己的ID？PHP Scoped输出缓冲区，如何？

所以，我有一个缓冲区的HTML页面，但也有一个页面内容连接a hook。钩子本身也包含输出缓冲：

<?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()刚刚停止输出缓冲区中的HTML页面。

那么，是否有可能有这样的机制？

<?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'); ?>

让每个ob_get_clean()都会有自己的价值：

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

我得到了这些错误：

我会尽量玩这个：http://php.net/manual/en/function.ob-get-level.php –

答

您需要的ob_get_clean值赋值给一个变量

<?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); ?>

请注意，我把引号$页面级>内容，以方便阅读这个代码，你应该不要使用这些引号。

是的，我确实把输出内容放在每次输出变量缓冲区结束。这就是我使用输出缓冲区的原因。但我不知道为什么有这个错误信息。 –
