How can PHP be used to filter query results based on dropdown selection values?

To filter query results based on dropdown selection values in PHP, you can use the $_GET superglobal variable to retrieve the selected value from the dropdown menu. Then, you can incorporate this value into your SQL query as a condition to filter the results accordingly. This allows you to dynamically adjust the query results based on the user's selection from the dropdown menu. 

<?php
// Retrieve the selected value from the dropdown menu
$selectedValue = $_GET['dropdown'];

// Use the selected value as a condition in your SQL query
$sql = "SELECT * FROM table_name WHERE column_name = '$selectedValue'";

// Execute the query and fetch the results
$result = mysqli_query($connection, $sql);

// Display the filtered results
while($row = mysqli_fetch_assoc($result)) {
    // Output the results as needed
}
?>
