Are there any best practices for handling multiple checkbox selections in PHP contact forms?

When handling multiple checkbox selections in PHP contact forms, it is important to ensure that the selected values are processed correctly. One common approach is to use an array to store the selected values and then iterate through the array to handle each selection individually. This allows for easy validation and processing of multiple checkbox selections.

// Process multiple checkbox selections in PHP contact form
if(isset($_POST['checkboxes'])) {
    $selectedValues = $_POST['checkboxes']; // Store selected values in an array

    foreach($selectedValues as $value) {
        // Handle each selected value individually
        // Perform any necessary validation or processing here
    }
}
