Php从所需文件中获取变量

Question

I have a class:

class My_Class {

    private $playlist_table_name;

    public function __construct() {

        $this->playlist_table_name = "something";

        require_once('markup.php');

    }

}

How do I access $playlist_table_name from markup.php file?

I tried using: $this->playlist_table_name, but I get:

Using $this when not in object context

Answer 1

If you want to access the variable like that, you will need to mark it as public

class My_Class {
    public $playlist_table_name;

    public function __construct() {
        $this->playlist_table_name = "something";

        require_once('markup.php');
    }
}

You are then going to want to instantiate the class before attempting to use it.

$MyClass = new My_Class;

echo $MyClass->playlist_table_name;

That will allow you to echo out the value.
