How can PHP be used to calculate sums between specific dates in a database query?

To calculate sums between specific dates in a database query using PHP, you can use SQL queries with the SUM() function along with the WHERE clause to filter the data based on the specified dates. You can pass the start and end dates as parameters to the query to dynamically calculate the sums within the specified date range. 

<?php
// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Specify the start and end dates
$start_date = '2022-01-01';
$end_date = '2022-01-31';

// Prepare and execute the query to calculate the sum between specific dates
$query = $pdo->prepare("SELECT SUM(amount) AS total_amount FROM your_table WHERE date BETWEEN :start_date AND :end_date");
$query->bindParam(':start_date', $start_date);
$query->bindParam(':end_date', $end_date);
$query->execute();

// Fetch the result
$result = $query->fetch(PDO::FETCH_ASSOC);

// Output the total sum
echo 'Total sum between ' . $start_date . ' and ' . $end_date . ': ' . $result['total_amount'];
?>
