How can one retrieve data from a MySQL database that falls within a specific calendar week using PHP?

To retrieve data from a MySQL database that falls within a specific calendar week using PHP, you can use the MySQL WEEK() function in your query. This function returns the week number for a given date, which can be used to filter the data based on a specific week. You can then pass the desired week number as a parameter to the WEEK() function in your SQL query to retrieve data for that particular week. 

// 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);
}

// Define the specific week number
$week_number = 42;

// Retrieve data for a specific week
$sql = "SELECT * FROM your_table_name WHERE WEEK(your_date_column) = $week_number";
$result = $conn->query($sql);

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

$conn->close();
