How can a filter be implemented to modify a MySQL query in PHP?

To modify a MySQL query in PHP using a filter, you can use PHP variables to dynamically construct the query based on user input or other conditions. This can help prevent SQL injection attacks and allow for more flexibility in querying the database. 

// Assuming $filterValue is the value you want to filter by
$filterValue = $_POST['filter_value'];

// Construct the query with the filter
$query = "SELECT * FROM table_name WHERE column_name = '" . $filterValue . "'";

// Execute the query using mysqli or PDO
$result = mysqli_query($connection, $query);

// Process the result set as needed
