How can PHP developers avoid errors when passing array values as parameters in functions?

To avoid errors when passing array values as parameters in functions, PHP developers should ensure that the function can handle arrays as input. This can be achieved by checking if the parameter is an array using the `is_array()` function before processing it within the function. Additionally, developers can provide default values or handle different types of input gracefully to prevent errors. 

function processArrayValues(array $values) {
    if (!is_array($values)) {
        throw new InvalidArgumentException('Input must be an array');
    }

    // Process the array values here
}

// Example usage
$values = [1, 2, 3];
processArrayValues($values);
