How to connect via PHP 8.1 PDO to old Microsoft SQL Servers:

Connecting to Microsoft SQL Server with PHP 8.1 PDO

PHP’s PDO (PHP Data Objects) extension provides a consistent and secure way to connect to various databases, including Microsoft SQL Server. In this tutorial, we’ll show you how to connect to an old Microsoft SQL Server using PHP 8.1 PDO and a class called DB.php.

Step 1: Download

Step 1: Download and Install the SQL Server Driver for PHP

First, you need to download and install the SQL Server Driver for PHP on your server. You can download the latest version of the driver from Microsoft’s official website.

Step 2: Create a new PHP Class called DB.php

Create a new PHP class called DB.php in your project directory, and paste the following code:

<?php

class DB {

private $serverName = “your_server_name”;

private $dbUsername = “your_username”;

private $dbPassword = “your_password”;

private $dbName = “your_database_name”;

private $conn;

public function __construct()

{

try {

$this->conn = new PDO(“sqlsrv:Server=$this->serverName;Database=$this->dbName”, $this->dbUsername, $this->dbPassword);

$this->conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

} catch (PDOException $error) {

die(“Diego we have an Error connecting to SQL Server: ” . $error->getMessage());

}

}

public function getConnection()

{

return $this->conn;

}

}

Replace “your_server_name”, “your_username”, “your_password”, and “your_database_name” with your actual server name, username, password, and database name.

Step 3: Connect to Microsoft SQL Server with DB.php

To connect to Microsoft SQL Server using DB.php, simply include the class file in your PHP script and create a new instance of the DB class. For example:

<?php

require_once ‘DB.php’;

$db = new DB();

$conn = $db->getConnection();

// Perform SQL queries here using $conn

?>

Step 4: Perform SQL Queries

Once you’ve connected to Microsoft SQL Server with DB.php, you can perform SQL queries using the $conn object. Here are some examples:

<?php

// SELECT query

$stmt = $conn->query(‘SELECT * FROM your_table_name’);

$results = $stmt->fetchAll(PDO::FETCH_ASSOC);

// INSERT query

$stmt = $conn->prepare(‘INSERT INTO your_table_name (column1, column2) VALUES (:value1, :value2)’);

$stmt->bindParam(‘:value1’, $value1);

$stmt->bindParam(‘:value2’, $value2);

$stmt->execute();

// UPDATE query

$stmt = $conn->prepare(‘UPDATE your_table_name SET column1 = :value1 WHERE column2 = :value2’);

$stmt->bindParam(‘:value1’, $value1);

$stmt->bindParam(‘:value2’, $value2);

$stmt->execute();

// DELETE query

$stmt = $conn->prepare(‘DELETE FROM your_table_name WHERE column1 = :value1’);

$stmt->bindParam(‘:value1’, $value1);

$stmt->execute();

?>

Note: Don’t forget to replace “your_table_name”, “column1”, and “column2” with your actual table name and column names.

Step 5: Close the Connection

When you’re finished with your SQL queries, you should close the connection to Microsoft SQL Server using the close() method. For example:

<?php

$conn =
