What are the best practices for handling and storing multiple selections from a form in PHP?

When handling and storing multiple selections from a form in PHP, it is best to use an array to store the selected values. This allows you to easily loop through the array and process each selection individually. You can then store the array in a database or session variable for future use. 

// Assuming the form input name is 'selections[]'
$selectedValues = $_POST['selections'];

// Loop through the selected values
foreach ($selectedValues as $value) {
    // Process each selection individually
    // For example, store in a database or perform some action
}

// Store the array in a session variable for future use
$_SESSION['selectedValues'] = $selectedValues;
