Starting with PHP & MySQL
PHP and MySQL are part of famous LAMP ( Linux , Apache, MySQL, PHP)
combination and is most popular database in use for the web applications. PHP
and MySQL gets integrated easily in any platformes. Scripts developed in PHP
using Window platform works perfectly in when used in Linux environment. Many
PHP MySQL developers work in Windows platform and run the script in Linux web
PHP: It is the script or language
PHP is used to connect to database, display the results or manage the records of the database. PHP is the server side scripting language and to know more about it and how PHP
work you can vist our PHP introduction page. To get the full detail of PHP
components working in the server you can use PHP command phpinfo. PHP works equally well with MSSQL, Oracle and other databases available. We will discuss more on MySQL here.
MySQL: It is the database
It stores tables, support queries to manage its data. We keep all our records in MySQL database. MySQL can be downloaded from www.mysql.org.
MySQL database is very powerful and can be used in real word demanding
projects. Different version of MySQL is available for different platforms.
MySQL once installed runs as a server in the local machine or in any remote
server. User can connect to the local or remote MySQL server by using the server
name or IP address based on the privelage they have. Once connected users can
manupulate the MySQL database by using different PHP commands. You will learn
many such PHP commands here.
Installing both depends on the platform you use. In windows system like any other software you can install both. Read the PHP section on how to install
After installing MySQL and your localhost, you can manage MySQL database by using PHPmyAdmin . Once our setup is ready we will try to run our SQL from PHP scripts
We will learn how to write a query and using PHP function how to execute the query. This process will ensure that all data connections are established and from PHP script we can manage the data stored in MySQL.
We will start with the most simple job of displaying records or data from MySQL table by using PHP. There are several ways to do this and as per our requirement we can collect single or multiple records from the tables to display.
Each record will have one Edit button for the user to update data
We can display minimal information line name or id to the user and on click we can further expand it to display full details of the record.
When we have more records to display we cant show all at same time. We can display fixed numbers or a set of records per page by giving navigation to previous or next set of records. We call it paging.
We can use PDO to connect to various data sources and we will discuss more on MySQL connection here
