What is the best practice for querying a database in PHP to check for specific events, like birthdays, and display corresponding content?

When querying a database in PHP to check for specific events like birthdays, you can use SQL queries to retrieve the relevant data based on the current date. You can then use PHP to process the results and display the corresponding content on your website. 

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// Query the database for birthdays
$currentDate = date("m-d");
$sql = "SELECT name, birthday FROM users WHERE DATE_FORMAT(birthday, '%m-%d') = '$currentDate'";
$result = $conn->query($sql);

// Display the corresponding content
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "Today is " . $row["name"] . "'s birthday!";
    }
} else {
    echo "No birthdays today.";
}

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