问题描述
header("Content-type: text/css"); 适用于 Firefox、Chrome 等，但不适用于 Internet Explorer 9.我不确定发生了什么.
header("Content-type: text/css"); works in Firefox, Chrome and other, but not in Internet Explorer 9. I am not sure what's up.
在 Chrome 和 Firework 中，如果我在自己的选项卡中打开样式表并将其应用于页面，它会显示样式表.
In Chrome and Firework it shows the style sheet if I open it in its own tab and it's being applied to the page.
在开发者工具中网络下的 Chrome 中，它显示类型为 text/css，状态为 200.
In Chrome under Network in the developer tools it says the type is text/css and the status is 200.
在 Internet Explorer 9 中，如果我在自己的选项卡中打开样式表并且它没有被应用到页面，它想要下载样式表.
In Internet Explorer 9, it wants to download the style sheet if I open it in its own tab and it's not being applied to the page.
在 F12 开发者工具中，您可以点击网络，开始捕获并刷新页面.它显示了 Style.css.php.类型为text/html，结果为406.
In the F12 developer tools you can click on network, start capturing and refresh the page. It shows the Style.css.php. The type is text/html and the result is 406.
这是在头脑中:
<link rel="stylesheet" type="text/css" href="/assets/css/style.css.php" media="screen" />

推荐答案
IE有不，我不是在开玩笑 Content-Type" 开关:
X-Content-Type-Options: nosniff
顺便说一句:确保您还发送 Last-Modified 并在 PHP 中禁用 session.cache_limiter，否则浏览器将不断重新加载 CSS 文件，这将对性能产生负面影响.
BTW: make sure you also send Last-Modified and disable session.cache_limiter in PHP, otherwise browsers will keep reloading the CSS file, which will negatively impact performance.
