I want to know what\'s the main difference between XAMPP or WAMP Server & IIS Server?
XAMPP is more powerful and resource taking than WAMP.
WAMP provides support for MySQL and PHP.
XAMPP provides support for MYSQL, PHP and PERL
XAMPP also has SSL feature while WAMP doesnt.
If your applications need to deal with native web apps only, Go for WAMP.
If you need advanced features as stated above, go for XAMPP.
As of priority, you cant run both together with default installation as XAMPP gets a higher priority and it takes up ports. So WAMP cant be run in parallel with XAMPP.
