If return statement is called from within a function, it immediately ends execution of the current function, and returns its argument as the value of the function call. If it is called from the global scope, then execution of the current script file is ended. If the current script file was included, then control is passed back to the calling file. Furthermore, if the current script file was included, then the value given to return will be returned as the value of the include call.
If return is called from within the init.php file, then script execution ends.
