在PHP中使用函数添加CSS

Question

I was try to add CSS file to my html file using statistic function like this:

      public static function addCSS($file){
         $cssPath = $_SERVER['DOCUMENT_ROOT']. DIRECTORY_SEPARATOR. 'new'. 
         DIRECTORY_SEPARATOR. 'css/'.$file;
           return file_exists($cssPath) ? "
   <link rel=\"stylesheet\" href=\"$cssPath\" type=\"text/css\" 
    media=\"screen\" charset=\"utf-8\" />
    " : "CSS File not found";
        }

but it doesn't work as i expected. i want it to produce the CSSPath like "http:localhost/new/css/admin.css when I'm called using General::addCSS('admin.css'); but all i got is address like this which make me fail to include: C:/xampp/htdocs ew\css/admin.css. how can i fix this addressing?

Answer 1

You are using xampp, so the document root path will be from that "Server". Thats why the path is wrong. you will need to exclusively specify what path you want, until you move to your server.

Also, if you are using a shared hosting plan, document root will not work most of the time. Set up a Constant with the server root path so that you can use it just like you use DOCUMENT_ROOT.

     //Create root path
     define('ROOT', 'something/anotherthing/public_html');

     public static function addCSS($file){
     //use root path everywhere instead of document_root
     $cssPath = ROOT . DIRECTORY_SEPARATOR. 'new'. 
     DIRECTORY_SEPARATOR. 'css/'.$file;
       return file_exists($cssPath) ? "
     <link rel=\"stylesheet\" href=\"$cssPath\" type=\"text/css\" media=\"screen\" charset=\"utf-8\" />
     " : "CSS File not found";
    }
