What MySQL function can be used to determine the week number of a given date for creating weekly statistics in PHP?

To determine the week number of a given date for creating weekly statistics in PHP, you can use the MySQL function WEEK(). This function returns the week number for a given date according to the ISO-8601 standard, which defines the first week of the year as the one that contains the first Thursday. Here is a PHP code snippet that demonstrates how to use the WEEK() function in a MySQL query to retrieve the week number for a given date: 

<?php
// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Define the date for which you want to get the week number
$date = "2022-01-15";

// Query to get the week number for the given date
$query = "SELECT WEEK('$date') AS week_number";

// Execute the query
$result = $mysqli->query($query);

// Fetch the result
$row = $result->fetch_assoc();

// Output the week number
echo "Week number for $date: " . $row['week_number'];

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