What are the potential pitfalls of using a maximum function in PHP?

One potential pitfall of using a maximum function in PHP is that it may not handle arrays with non-numeric values properly, leading to unexpected results or errors. To solve this issue, you can use the `max` function with the `array_map` function to convert all values to integers before finding the maximum value. 

$values = [10, 20, '30', 40];
$numericValues = array_map('intval', $values);
$maxValue = max($numericValues);

echo $maxValue;
