Dynamic website tools: PHP and MySQL
Creating a dynamic website is a must if you want your web site to be a success. Web visitors are no longer satisfied with web pages that don't offer any interactivity or fresh content on a regular basis. The PHP and MySQL combination has made it easier than ever to design and program an interactive, dynamic web site.
The first thing that you must do when creating a dynamic site with PHP and MySQL is to create a MySQL database. Once you have set up a MySQL database with tables and fields, you will need to connect to the MySQL database with PHP scripts.
If you don't successfully connect to the database, any commands that you write will fail. When you begin to write your script, the first thing you should do is specify your database name, user name and password. If you have to change any of the things later, only one line of the script will have to be changed.
Keeping your password and user name in your PHP file is secure because the source code is is processed before it is sent to the browser as html, so no one that views the source code will see the sensitive information.
After you have specified your database name, your user name and your password, you will execute a command to open a database connection. After you write your first command, you will need to make sure that you close your command. Your scripts will work if you don't use a command close, but your web host could see some major problems if you have too many open MySQL connections.
If you have more than one database on your server, you will need to make sure that you have specified the correct database. Your user name must have access to whatever database you choose to connect to.
Once you have your database connection, you can begin to work with your dynamic web site. Two ways of providing dynamic content are available to you. The first is to simply enter a PHP command. If there are no results from the operation, this is a fine option. If you want different results each time the script runs, you should define the comment as a variable.
You can repeat this command many times without taking the time to learn a lot of PHP commands. You can have a lot of different results with this command: mysql_query($query); . This command is one of the most versatile commands when using PHP and MySQL to create a dynamic website.
Creating a dynamic web site with PHP and MYSQL is within reach of most people, including hobbyists and people that are interested in having a spectacular personal site. MySQL and PHP are free to download and most webhosts support the languages. Understanding the concepts behind the PHP and MySQL connection can make it easier for you to understand your blogging software and can help you personalize your own blogs and interactive forums much more easily.
