Are regular expressions a better alternative to in_array for validating checkbox selections in PHP?

Regular expressions can be a more powerful and flexible alternative to in_array for validating checkbox selections in PHP. By using regular expressions, you can define specific patterns that the checkbox values must match, providing more control over the validation process. This can be particularly useful when dealing with complex or dynamic checkbox selections. 

// Example code using regular expressions for validating checkbox selections
$checkboxValues = $_POST['checkbox_values'];

// Define a regular expression pattern for valid checkbox values
$pattern = '/^(value1|value2|value3)$/';

// Check if all checkbox values match the pattern
if (preg_match($pattern, $checkboxValues)) {
    // Checkbox selections are valid
    echo "Checkbox selections are valid.";
} else {
    // Checkbox selections are invalid
    echo "Invalid checkbox selections.";
}
