How can PHP handle multiple date selection criteria from HTML forms to fetch corresponding database records?

When handling multiple date selection criteria from HTML forms in PHP to fetch corresponding database records, you can use the `$_POST` superglobal array to retrieve the selected dates. You can then construct a SQL query using these dates as conditions to fetch the desired records from the database.

<?php
// Retrieve selected dates from HTML form
$date1 = $_POST['date1'];
$date2 = $_POST['date2'];

// Construct SQL query with date conditions
$sql = "SELECT * FROM table_name WHERE date_column BETWEEN '$date1' AND '$date2'";

// Execute the query and fetch records
// $result = mysqli_query($connection, $sql);
// while ($row = mysqli_fetch_assoc($result)) {
//     // Process fetched records
// }
?>
