How can PHP be used as a bridge between VB and MySQL for data retrieval and display?

To use PHP as a bridge between VB and MySQL for data retrieval and display, you can create a PHP script that connects to the MySQL database, retrieves the data, and then outputs it in a format that can be easily consumed by VB. This script can be accessed via a HTTP request from VB to fetch the data. 

<?php
// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Retrieve data from MySQL
$sql = "SELECT * FROM table";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data in JSON format
    $data = array();
    while($row = $result->fetch_assoc()) {
        $data[] = $row;
    }
    echo json_encode($data);
} else {
    echo "0 results";
}

$conn->close();
?>
