Hye Nahid Bin Rahman They are built-in variables that are always available in all scopes. And yeah you can access them from any class,function or file without having to do anything precious. There are the variables of superglobals too. $GLOBALS $_SERVER $_GET $_POST $_FILES $_COOKIE $_SESSION $_REQUEST $_ENV I hope this links will too help - https://www.geeksforgeeks.org/php-superglobals/ http://www.nusphere.com/php/php_superglobals.htm http://www-db.deis.unibo.it/courses/TW/DOCS/w3schools/php/php_superglobals.asp.html https://www.tutorialspoint.com/php/php_predefined_variables.htm https://www.phptpoint.com/php-super-global-variables/ I hope this helps ✌️

A global variable is not accessible by default in a function scope. There is need to explicitly use the global keyword. But superglobals can be used without explicitly using global keyword. Piyush has already done a good job in listing the built-in superglobals.
