Unbreakable most secure password generator using AJAX, PHP

Описание: Unbreakable most secure password generator using AJAX and php.
Using php create a word string A-Za-z0-9(*&@!=×)
and use inbuilt functions substr for extracting sub string from word string and str_shuffle for shuffling characters inside word string.
echo substr(str_shuffle($word),0,10);
Ajax is used to send and receive data without refreshing page.

Thank You.
