How can PHP be used to filter database queries for only active data records?

To filter database queries for only active data records, you can add a condition to your SQL query that checks for a specific column indicating the record's active status. This column could be a boolean field like 'is_active' where 1 represents active records and 0 represents inactive records. By adding this condition to your query, you can ensure that only active data records are retrieved. 

// 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);
}

// Select only active records from the database
$sql = "SELECT * FROM table_name WHERE is_active = 1";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
