How To Build a Website using PHP and MySQL

PHP stands for “Hypertext Preprocessor” and is a widely-used open-source scripting language. It is famous for generating dynamic web content that interacts with databases. With PHP in web development, you are not just limited to HTML; you can even output pdf files, any text (XML, XHTML) images, and flash files

Why PHP?

One unique feature of PHP is that it executes the scripting code on the server, generating the HTML. The response is sent back to the client. The client can receive the result of managed scripting code without performing the underlying code. This one factor distinguishes PHP from other programming languages and serves as a helping hand to the developers.

This way, developers can easily configure the web server in order to process required HTML files (including PHP script).

We are now coming back to our former question, how to serve your website with PHP MySQL web development?

PHP with a database system (MySQL)

In the form of scripting language, PHP is popular among enterprises and web developers due to its ability to interact with several database systems like MySQL and Oracle. In this article, we will discuss the integration of PHP with the MySQL database system.

Any business website needs a certain amount of information or data for display and retrieval. The data is retrieved from the database and can include anything from a simple list to a complex website running data process.

Following are some of the most common examples where PHP can be used with MySQL efficiently:

●    Digital boards or Internet forums-

Here PHP and MySQL can be used to store and retrieve user messages.

●    Digital Ad banners-

A PHP script can be utilized here to retrieve a digital banner from the database. Furthermore, the system selects a random banner from the records and addresses it back to the calling script.

Here, the PHP script can also view and manage banner records and clicks from the website.

●   Website designing-

You can change the design of your entire website with PHP scripts. Instead of modifying and uploading every single web page, PHP gives you the flexibility to change the complete website design in one go by integrating a couple of PHP scripts.

In addition to this, PHP script can also access the MySQL database to retrieve all information regarding the website.


Set Up Your MySQL Database:

The process of setting up MySQL database changes with the host. Every database needs username and password credentials to access other databases.

The database administration can be completed by using a program like PHPMyAdmin or using PHP scripts.

The next step is to generate database tables to store the website information. If you wish to create a database table with PHPMyAdmin, even that is simple.

You can do this process alternatively and further configure the entire database with the PHP script given below:

CREATE TABLE tablename {



Where the fields require a coded name, type field name type(length) extra_info

For instance- first varchar(15) NOT NULL

You can then use the following command to connect your PHP script to the MySQL database


In the above command,

  • Localhost is the server address to run the website.
  • $username is the username used for database access.
  • $password is the password used for database access.

PHP commands execution

When you finally configure and connect to the MySQL database, it’s time to execute PHP commands on the server.

Following are two required methods to successfully execute a PHP command:

  1. Enter the command in PHP through the below syntax



You can repeat this command for another display by simply changing the variable.

  1. Another step is to define the command as a variable. This way, the result of the entire operation will be assigned to the variable.

Data Input and Output

The data insertion using PHP is very similar to data input using HTML pages. One benefit that you get over PHP is that you do not need to change the script every time you input new data.

You can use text boxes in HTML to input data, such as,

<form action=”insert.php” method=”post”>

First Name: <input type=“text” name=“first”><br>

As discussed above, alternatively you can also perform variables to input info in the database, like:








$query= “INSERT INTO contact VALUES(,’$first’,’$last’,’$mobile’,’$fax’,’$email’,’$web’,);”



You save this script in the insert.php file. Using this syntax, the data is stored in the defined variables, which are then passed on to PHP.

In order to display, the entered data in the PHP, follow:

$query= “SELECT” FROM “contacts”


After this, PHP offers two submission methods, POST and GET to get the data into your PHP script.


  • “GET” will display the variables in the page address.
  • In the POST method, the variables are invisible


MySQL is a robust database that meets nearly all the requirements of client-server applications. In any way, it can be a double blessing to equip yourself with both PHP and MySQL. Speaking of which, if you find any technical challenges while performing the PHPMySQL web development, we would suggest you hire expert PHP developers for a smooth process.
