How can PHP be used to dynamically display unique BID values and their corresponding data entries from a database?

To dynamically display unique BID values and their corresponding data entries from a database using PHP, you can query the database for distinct BID values and then loop through each unique BID to retrieve and display their corresponding data entries. This can be achieved by using SQL queries to fetch the distinct BID values and then fetching the corresponding data entries for each unique BID. 

<?php
// Connect to the 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);
}

// Query to fetch distinct BID values
$sql = "SELECT DISTINCT BID FROM your_table_name";
$result = $conn->query($sql);

// Loop through each unique BID
while ($row = $result->fetch_assoc()) {
    $bid = $row['BID'];

    // Query to fetch corresponding data entries for each unique BID
    $data_sql = "SELECT * FROM your_table_name WHERE BID = $bid";
    $data_result = $conn->query($data_sql);

    // Display the BID value
    echo "BID: " . $bid . "<br>";

    // Display the corresponding data entries
    while ($data_row = $data_result->fetch_assoc()) {
        echo "Data: " . $data_row['column_name'] . "<br>";
    }
}

// Close the connection
$conn->close();
?>
