How can CSS classes be effectively applied to alternate rows in a PHP-generated HTML table to improve visual differentiation?

To improve visual differentiation in a PHP-generated HTML table, CSS classes can be applied to alternate rows. This can be achieved by using PHP to dynamically add a class to every other row in the table, allowing for easy styling with CSS to create a visually appealing design. 

```php
<table>
<?php
$items = array("Item 1", "Item 2", "Item 3", "Item 4", "Item 5");

foreach ($items as $key => $value) {
    $row_class = ($key % 2 == 0) ? 'even' : 'odd';
    echo "<tr class='$row_class'><td>$value</td></tr>";
}
?>
</table>
```

In the above code snippet, the `$row_class` variable is used to determine whether the current row should have the 'even' or 'odd' class applied based on the index of the row in the loop. This allows for easy styling of alternate rows using CSS to improve visual differentiation in the HTML table.
