在cakephp中如何创建另一个文件，如core.php文件，并在js文件中调用全局变量

I have created a file inside config folder similar like config.php. how can I call the global variables mentioned in my newconfigfile.php in my js file. for example define("DATETIME_FORMAT", "MM/dd/yy HH:mm");

Create a fie in your app/Vendor/newconfigfile.php then paste this line

define("DATETIME_FORMAT", "MM/dd/yy HH:mm");    

Now go to in your app/Config/bootstrap.php

Add the following line

App::import('Vendor', 'newconfigfile');

Now you can call DATETIME_FORMAT as a global variable.
