使所有的PHP文件输出都通过一个“过滤器文件”在显示之前 [英] Making all PHP file output pass through a "filter file" before being displayed
问题描述
如果有更好的方法来达到同样的结果,我很乐意知道。
谢谢。 nofollow noreferrer> ob_start ,它可以让你传递一个回调处理器来处理你的脚本输出。
$ b 例如,PHP包含一个内置的回调<一个用于压缩输出的href =http://php.net/ob_gzhandler =nofollow noreferrer> ob_gzhandler :
<?php
ob_start(ob_gzhandler);
?>
< html>
< body>
< p>这应该是一个压缩页面。< / p>
< / html>
< body>
下面是一个更完整的例子,说明如何使用 tidy extension :
function tidyhtml($ input)
{
$ config = array(
'indent'=> true,
'output-xhtml'=> true,
'wrap'=> 200);
$ tidy = new tidy;
$ tidy-> parseString($ input,$ config,'utf8');
$ tidy-> cleanRepair();
//输出
return $ tidy;
}
ob_start(tidyhtml);
//现在输出丑陋的HTML
如果您想确保所有你的PHP脚本使用相同的过滤器,而不直接包括它,检查 auto_prepend_file 配置指令。
Is there any way for all my PHP and/or HTML file output to be "filtered" before being displayed in the browser? I figured that I could pass it through a global function before it is displayed but I'm stuck on the implementation. Please help.
If there is a better way to achieve the same result, I'd be happy to know.
Thanks.
Check out ob_start which lets you pass a callback handler for post-processing your script output.
For example, PHP includes a built-in callback ob_gzhandler for use in compressing the output:
<?php
ob_start("ob_gzhandler");
?>
<html>
<body>
<p>This should be a compressed page.</p>
</html>
<body>
Here's a fuller example illustrating how you might tidy your HTML with the tidy extension:
function tidyhtml($input)
{
$config = array(
'indent' => true,
'output-xhtml' => true,
'wrap' => 200);
$tidy = new tidy;
$tidy->parseString($input, $config, 'utf8');
$tidy->cleanRepair();
// Output
return $tidy;
}
ob_start("tidyhtml");
//now output your ugly HTML
If you wanted to ensure all your PHP scripts used the same filter without including it directly, check out the auto_prepend_file configuration directive.
