CSS与PHP合并 [英] CSS merging with PHP

问题描述

我在网站上找到了这个网址，

I found this on a website,

css_loader.php

css_loader.php

<?php
// First of all send css header
header("Content-type: text/css");

// Array of css files
$css = array(
    'main.css',
    'menu.css',
    'content.css'
);

// Loop the css Array
foreach ($css as $css_file) {

    // Load the content of the css file 
    $css_content = file_get_contents($css_file);

    // print the css content
    echo $css_content;
}
?>

向页面添加CSS

<link href="css_loader.php" rel="stylesheet" type="text/css" />

看起来很合乎逻辑，但是当我将它应用到我的页面时，它没有工作。

It looks very logical but when i applied it to my page, it didnt work.

是否可以以这种方式合并CSS文件？

is that possible to merge CSS files with this way ?

推荐答案

您的代码中有错误，请输入正确的代码：

You have an mistake in your code, here's the correct code:

<?php
// First of all send css header
header("Content-type: text/css");

// Array of css files
$css = array(
    'main.css',
    'menu.css',
    'content.css'
);

// Prevent a notice
$css_content = '';

// Loop the css Array
foreach ($css as $css_file) {
    // Load the content of the css file 
    $css_content .= file_get_contents($css_file);
}

// print the css content
echo $css_content;
?>

我希望文件在同一个文件夹中。也许你应该使用 __ DIR __ 或 dirname（__ FILE __）来获取文件的相对路径。

And I hope the files are in the same folder. Perhaps you should use __DIR__ or dirname(__FILE__) to get the relative path to your files.
