MVC：如何存储公共变量以从PHP中的所有MVC相关文件进行访问

Question

I am learning MVC based web pages in php.I have few php files with multiple classes & methods in MVC layers.I have many variables & large arrays that need to be accessed in several files.some sample given below:

$label = array("lng"=>Language",tlabel"=>"Title", 
               "content"=>"Details", "tm"=>"Date", 
               "authr"=>"Post By");
$route_url;
$database;
$navbar_text;
$footer_text;

I saw few php example about using php keyword global. But using it in many parts of the code will become very messy to keep track.I also saw another technique where every common things goes inside a special class called Config like given below:

// does it need auto load? i don't know
class Config
{

    public static $label = array("lng"=>Language","tlabel"=>"Title", 
                                   "content"=>"Details", "tm"=>"Date", 
                                   "authr"=>"Post By");
    public static $route_url;
    public static $database;
    public static $navbar_text;
    public static $footer_text;

}

echo SmtpConfig::$label["tlabel"];

So, please suggest the correct way in which MVC web developer do such things.Thanks

Answer 1

You can use Static Class Variables.

The second approach to use $GLOBAL vars.

But it is not a good approach to use a lot of global variables.
