How can CSS affect the hover color of links generated by PHP loops?

When using PHP loops to generate links, each link will have a common class or selector that can be targeted with CSS to change the hover color. By adding a CSS rule for the hover state of the class or selector, you can specify a different color for when the links are hovered over. This will allow you to customize the hover color for all links generated by the PHP loop.

<?php
// PHP loop to generate links
for ($i = 1; $i <= 5; $i++) {
    echo '<a href="#" class="generated-link">Link ' . $i . '</a>';
}
?>
```

```css
<style>
.generated-link {
    color: blue; /* default link color */
}

.generated-link:hover {
    color: red; /* hover color for links generated by PHP loop */
}
</style>
