i wanted to know, good techniques of keeping your site from be hacked, or at least to a knowledgeable limit.
ive surfed the net, for securing websites, but what is a good coding language to you? js, php, mysql, etc

thanks in-advance

Depends on what you want to do.
JavaScript is used for making things pretty, it should never be used for authorisation because it can be disabled, altered and read by the user.
PHP is a good server-side scripting language though personally I prefer the power of CGI.
MySQL is a database server - you query it with SQL which is sent from a server side script, such as PHP.

In terms of stopping a site from "being hacked", there is one important rule to remember: "think twice, and never give your user more power than is required". Act as if everyone who will use your site is potentially malicious - validate and cleanse every scrap of input.
