Prerequisites for PHP With MySQL 

This PHP with MySQL tutorial will mainly focus on linking and managing a database with your webpage. Hence, the following prerequisites should be met before beginning the tutorial:

Software Requirements for the Tutorial

To set up the PHP development environment, you mainly need two software, a code editor and a web server package.

You will be using:

Now that you know the prerequisites for this tutorial as well and the software requirements, it’s time to move on to creating a database.

How to Create a Database?

A database is defined as an organized collection of data that makes the data easy to access, manage and modify. Generally, databases use SQL (Structured Query Language) for data manipulation.

To create a database:

1. Open XAMPP Control Panel and start the Apache server and MySQL service.

Keep the “id” column as Auto Incremented by clicking the check box next to ‘AI’ since it will be the primary key.

How to Create a Registration Page?

To create a registration, first, create a folder named “demo” inside htdocs and then open it inside the code editor i.e, Visual Studio Code.

Now, create a file named “register.php” and write the following code.

<?php 

include "config.php";

  if (isset($_POST['submit'])) {

    $first_name = $_POST['firstname'];

    $last_name = $_POST['lastname'];

    $email = $_POST['email'];

    $password = $_POST['password'];

    $gender = $_POST['gender'];

    $sql = "INSERT INTO `users`(`firstname`, `lastname`, `email`, `password`, `gender`) 

           VALUES ('$first_name','$last_name','$email','$password','$gender')";

    $result = $conn->query($sql);

    if ($result == TRUE) {

      echo "New record created successfully.";

    }else{

      echo "Error:". $sql . "<br>". $conn->error;

    }

    $conn->close();

  } 

?> 

<!DOCTYPE html>

<html>

<body>

<h2>Registration Form</h2> 

<form action="" method="POST">

  <fieldset>

    <legend>Information:</legend>

    First name:<br>

    <input type="text" name="firstname">

    <br>

    Last name:<br>

    <input type="text" name="lastname">

    <br>

    Email:<br>

    <input type="email" name="email">

    <br>

    Password:<br>

    <input type="password" name="password">

    <br>

    Gender:<br>

    <input type="radio" name="gender" value="Male">Male

    <input type="radio" name="gender" value="Female">Female

    <br><br>

    <input type="submit" name="submit" value="submit">

  </fieldset>

</form> 

</body>

</html>

That’s it. Now you just need to connect this webpage with the database.

How to Connect Webpage to the Database Using PHP?

To connect the webpage to the database, create another file in the code editor named “config.php” and write the following code.

<?php

    $servername = "localhost";

    $username = "root";

    $password = "";

    $dbname = "tutorial"; 

    $conn = new mysqli($servername, $username, $password, $dbname);

    if($conn->connect_error) {

        die("Connection Failed" . $conn->connect_error);

    }

?>

Now that you have the registration page ready and connected to the database, open the browser for the output.

  • Open the browser and type “localhost/demo/register.php”. Fill in the required fields and click on “submit”.

  • Now, go to the “users” table in the phpmyadmin panel and check for the data.

As you can see, the records are visible in the table “users”.

Now you know how to create a database and link it to a webpage. You will now see how to edit or delete the fields from the phpmyadmin control panel.

How to Edit and Delete Data From the Database?

Once data has been entered into the database, you can open the phpmyadmin panel from the XAMPP dashboard and locate to the table “users” where every information entered into the table is visible.

Here, with every data, there exists an edit and delete option which can be used to update or delete any desired data from the table.
