What is the best practice for passing multiple values to a PHP function and returning modified values?

When passing multiple values to a PHP function and needing to return modified values, it is best practice to use an associative array or an object to hold all the values as parameters. This way, you can easily pass and access multiple values within the function without the need to modify the function signature. After processing the values within the function, you can return the modified values in the same array or object. 

// Define a function that takes an associative array as a parameter and returns the modified values
function modifyValues(array $values): array {
    // Modify the values as needed
    $values['value1'] *= 2;
    $values['value2'] += 10;

    // Return the modified values
    return $values;
}

// Example usage
$inputValues = ['value1' => 5, 'value2' => 10];
$modifiedValues = modifyValues($inputValues);

// Output the modified values
print_r($modifiedValues);
