What is the best way to handle multiple select menu options in PHP for file naming?

When handling multiple select menu options in PHP for file naming, one approach is to concatenate the selected options into a single string separated by a delimiter. This allows you to create a unique file name based on the selected options. You can then sanitize the file name to remove any special characters or spaces before saving it. 

// Get the selected options from the multiple select menu
$selectedOptions = $_POST['options'];

// Concatenate the selected options into a single string separated by a delimiter
$fileName = implode('_', $selectedOptions);

// Sanitize the file name to remove any special characters or spaces
$fileName = preg_replace('/[^A-Za-z0-9_]/', '', $fileName);

// Save the file with the sanitized file name
file_put_contents('path/to/save/directory/' . $fileName . '.txt', 'File content here');
