Here is a link to a tutorial that will show you how to set up everything: http://www.freewebmasterhelp.com/tutorials/phpmysql/

PHP is server-side, the browser itself does not interpret it. Rather, the browser sends a query to the server, and the PHP scripting generates custom HTML document. It is this HTML that you are seeing the source code of.
I am not aware of JAVA to that scale but if you just want to fetch data from mysql then PHP is just 2 statements:Query Statement.

Using Mysql and php data can be retrieved from a database. In your php code mysql_query("YOUR QUERY HERE") will return the result of your query. This ust then be unpacked with other mysql commands like mysql_fetch_array($result) etc. Remember that PHP is a server side language meaning that it is completely executed before the page is displayed to the user. If your question is pertaining to something like Google Suggest, which suggests completions as you type, this requres the use of Javascript in addition to your scripting language of choice.
PHP allows for much more customization and interactivity. Take Google, for example. Without dynamic programming, Google would have to create every search result page by hand. With Python (similar to PHP), they can simply query their database for results.
A mysql query can be run with the mysql_query(); function. Unfortunately, php allows you to run a maximum of one query each time. A possibility is to write all your queries to an array();, and then have them applied in a foreach(); loop.
