PHP Database

To connect PHP with a database, you can use the PHP Data Object (PDO) extension or the MySQLi (MySQL Improved) extension. Both of these extensions provide a simple and effective way to connect to a database and perform common database operations such as executing SQL queries, inserting, updating and deleting records, and retrieving data from the database.

What we cover in this articles

We use PHP and MySQL

• Connect PHP and MySQL
• Configure database
• Install Laravel Breeze
• Install Livewire
• Implement CRUD operations
• Running the application

Setup Laravel project

To connect PHP with a database, you can use the PHP Data Object (PDO) extension or the MySQLi (MySQL Improved) extension. Both of these extensions provide a simple and effective way to connect to a database and perform common database operations such as executing SQL queries, inserting, updating and deleting records, and retrieving data from the database.

<?php
$host = 'hostname';
$dbname = 'database_name';
$username = 'username';
$password = 'password';
 
try {
    $conn = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    echo "Connected successfully";
    }
catch(PDOException $e)
    {
    echo "Connection failed: " . $e->getMessage();
    }
?>

Create Database

To create a database using PHP and MySQL, you can use the following steps:

Connect to the MySQL server: You can use either the PDO or MySQLi extension to connect to the MySQL server.

Execute a CREATE DATABASE query: Once you have established a connection to the MySQL server, you can use the exec() or query() method to execute a SQL query to create the database.

Here's an example of creating a database using PDO:

<?php
$host = 'hostname';
$dbname = 'database_name';
$username = 'username';
$password = 'password';
 
try {
    $conn = new PDO("mysql:host=$host", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $sql = "CREATE DATABASE $dbname";
    // use exec() because no results are returned
    $conn->exec($sql);
    echo "Database created successfully<br>";
    }
catch(PDOException $e)
    {
    echo $sql . "<br>" . $e->getMessage();
    }
 
$conn = null;
?>

Create Table

Insert Data

Implement CRUD Operations

• Running the application Now let's serve the application

php artisan serve
