              header.inc.php

              footer.inc.php

  index.php

  login.php

  register.php

style.css包含在header.inc.php

中

<?php

//Include a error reporting:

include '../../errorReport.inc.php';

// Set default timezone:

define('TZ', date_default_timezone_set('America/Los_Angeles') );

?>

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<head>

    <title>

    <?php

    if(defined('TITLE'))

    {

        print TITLE;

    } else {

        print 'Raise High the Roof Beam! A J.D. Salinger Fan Club';

    }



    ?>

    </title>

    <meta http-equiv="content-type" content="text/html; charset=utf-8" />

    <link rel="stylesheet" href="./c/screen.css" media="screen,projection" />

</head>

创建新页面（login.php）后，目标是在标题中的include（d）CSS中添加样式。不只是将css放在标记的任何地方，以下是我的尝试，它失败了：

<?php

header('content-type:text/css', replace);

header("Expires: ".gmdate("D, d M Y H:i:s", (time()+900)) . " GMT");

$errorColor = '#900';

echo '.error{ color: '.$errorColor.'; }';

?>

<?php include 'inc/header.inc.php';?>

<p class=\"error\">Error MSG</p>

<?php include 'inc/footer.inc.php';?>

这是打印到UA：

.error{ color: #900; }
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

    <meta http-equiv="content-type" content="text/html; charset=utf-8" />
    <link rel="stylesheet" href="./c/screen.css" media="screen,projection" />

Answer 1

简单的答案是，您应该在样式表style.css中包含此CSS，因为它是常量。

如果您希望这是动态的，则需要稍微修改一下您的方案。这是一个框架将有用的地方，因为你做出的任何选择都将是一个黑客攻击。话虽如此，请考虑以下选项：

A）在login.php中设置$headerCss = '.error { color: '.$errorColor.'; } '，然后在header.inc.php中，在</head>标记之前添加：

if ($headerCss) {
    print '<style type="text/css">';
    print $headerCss;
    print '</style>';
}

B）另一个可能的黑客是设置$pageName = 'login'，然后有一个开关来测试header.inc.php中的页面名称，如：

if ($pageName == 'login') {
    print '<style type="text/css">';
    print '    .error { color: #900; }';
    print '</style>';
}

Answer 2

.error{ color: #900; }需要位于<style>内的<head>标记内，而不是文档的最顶部。

<?php
    header('content-type:text/css', replace);
    header("Expires: " . gmdate("D, d M Y H:i:s", (time()+900)) . " GMT");

    $errorColor = '#900';
    $css        = array();
    $css[]      = '.error{ color: '.$errorColor.'; }';
?>

<?php include 'inc/header.inc.php';?>
<p class="error">Error MSG</p>
<?php include 'inc/footer.inc.php';?>

然后，在inc/header.inc.php内，在<head>标记中包含类似内容：

if (is_array($css)) {
    echo '<style type="text/css">' . implode("\n", $css) . '</style>';
}

已更新至以下内容：inc / header.inc.php：

<?php 
//Include a error reporting:
include '../../errorReport.inc.php'; 
// Set default timezone:
define('TZ', date_default_timezone_set('America/Los_Angeles') );
?>
