有没有办法让我的所有 PHP 和/或 HTML 文件输出在显示在浏览器中之前被过滤"?我想我可以在它显示之前通过一个全局函数传递它,但我被困在实现上.请帮忙.
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.
如果有更好的方法来实现相同的结果,我很乐意知道.
If there is a better way to achieve the same result, I'd be happy to know.
谢谢.
查看 ob_start 它可以让您通过用于后处理脚本输出的回调处理程序.
Check out ob_start which lets you pass a callback handler for post-processing your script output.
例如,PHP 包含一个内置回调 ob_gzhandler 用于压缩输出:
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>
这是一个更完整的示例,说明如何使用 tidy 扩展:
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
如果您想确保所有 PHP 脚本使用相同的过滤器而不直接包含它,请查看 auto_prepend_file 配置指令.
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.
