Are you ready to connect your PHP files to a MySQL database? Whether you're a beginner or looking for a refresher, this guide will walk you through the entire process using phpMyAdmin. We'll cover everything from setting up your database to performing essential CRUD (Create, Read, Update, Delete) operations.




What You Need


Before diving in, ensure you have the following:


  • XAMPP or a similar web server installed on your computer. This will allow you to run PHP and MySQL locally.
  • A code editor like VS Code or Sublime Text to write your PHP scripts.
  • A web browser to access phpMyAdmin and view your database.

Step 1: Starting XAMPP


  1. Open the XAMPP Control Panel.
  2. Start Apache and MySQL by clicking the "Start" button next to each.
  3. Your local server is now running and ready for use!

Step 2: Accessing phpMyAdmin


  1. Open your web browser and type http://localhost/ in the address bar.
  2. Look for phpMyAdmin and click on it.
  3. This will open the phpMyAdmin interface, where you can manage your databases.

Step 3: Creating a Database


  1. In phpMyAdmin, click on the "Databases" tab.
  2. In the "Create database" field, type a name for your new database (e.g., phpcrud).
  3. Click the "Create" button.
  4. Your database is now set up and ready to use!

Step 4: Importing Data (Optional)


If you already have an SQL file with data, you can import it:


  1. Click on your new database (phpcrud).
  2. Go to the "Import" tab.
  3. Click "Choose File" and select your .sql file.
  4. Scroll down and click "Go".
  5. Your database will now be populated with the imported data.

Step 5: Connecting PHP to the Database


Now, let’s establish a connection between PHP and MySQL.


  1. Open your config.php file in your code editor.
  2. Use the following code to connect PHP to MySQL:
<?php
$servername = "localhost";
$username = "root";
$password = ""; // Leave blank if no password is set
$database = "phpcrud";


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


// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
else {
    echo "Connected successfully!";
}
?>

  1. Save the file and run it in your browser.
  2. If everything is set up correctly, you should see "Connected successfully!".

Step 6: Performing CRUD Operations


Once your database connection is established, you can perform CRUD operations using SQL queries.


Create (Add Data)


To add new data, use an INSERT query:


$sql = "INSERT INTO employees (name, address, salary) VALUES ('John Doe', '123 Main St', 50000)";

$conn->query($sql);

Alternatively, in phpMyAdmin:


  1. Click on your table.
  2. Go to the "Insert" tab.
  3. Fill in the details and click "Go".

Read (View Data)


To retrieve data from your table, use a SELECT query:


$sql = "SELECT * FROM employees";

$result = $conn->query($sql);

Or, in phpMyAdmin:


  1. Click on your table.
  2. Go to the "Browse" tab to see all records.

Update (Edit Data)


To modify existing data, use an UPDATE query:


$sql = "UPDATE employees SET salary = 60000 WHERE name = 'John Doe'";

$conn->query($sql);

In phpMyAdmin:


  1. Click on your table.
  2. Click the "Edit" icon next to the record.
  3. Modify the values and click "Go".

Delete (Remove Data)


To delete a record, use a DELETE query:


$sql = "DELETE FROM employees WHERE name = 'John Doe'";

$conn->query($sql);

In phpMyAdmin:


  1. Click on your table.
  2. Click the "Delete" icon next to the record.

Example: Managing Employee Data


Let’s say you have an employees table with columns like name, address, and salary. Using phpMyAdmin, you can:


  • Add a new employee by clicking "Insert" and filling in the details.
  • View an employee’s details by clicking on the table and browsing records.
  • Edit an employee’s information by clicking the "Edit" icon.
  • Delete an employee by clicking the "Delete" icon.

These actions help you manage your MySQL database effortlessly!
