PHP-如何在包含header.php之后更改页面标题? [英] PHP - how to change title of the page AFTER including header.php?

问题描述

page.php:

<?php
include("header.php");
$title = "TITLE";
?>

header.php:

header.php:

<title><?php echo $title; ?></title>

我希望在包括头文件之后设置我的标题.是否有可能做到这一点?我在php-fusion电视上看到了一些类似的东西: http://docs.php-fusion.it/temi:output_handling

i want my title to be set AFTER including the header file. Is it possible to do this? I've seen some similiar stuff on php-fusion tvs: http://docs.php-fusion.it/temi:output_handling

推荐答案

扩展Dainis Abols答案以及您对输出处理的问题，

expanding on Dainis Abols answer, and your question on output handling,

请考虑以下内容:

您的header.php的标题标签设置为<title>%TITLE%</title>; ％"很重要，因为几乎没有人键入％TITLE％，因此您以后可以将其用于str_replace().

your header.php has the title tag set to <title>%TITLE%</title>; the "%" are important since hardly anyone types %TITLE% so u can use that for str_replace() later.

然后，您可以使用输出缓冲区像这样

then, you can use output buffer like so

<?php
    ob_start();
    include("header.php");
    $buffer=ob_get_contents();
    ob_end_clean();

    $buffer=str_replace("%TITLE%","NEW TITLE",$buffer);
    echo $buffer;
?>

那应该做到的.

编辑

我相信盖伊的想法效果更好，因为它会在需要时为您提供默认值，即IE:

I believe Guy's idea works better since it gives you a default if you need it, IE:

• 标题现在为<title>Backup Title</title>
• 代码现在为:

<?php
    ob_start();
    include("header.php");
    $buffer=ob_get_contents();
    ob_end_clean();

    $title = "page title";
    $buffer = preg_replace('/(<title>)(.*?)(<\/title>)/i', '$1' . $title . '$3', $buffer);

    echo $buffer;
?>
