How can alternating row colors be implemented in a PHP and MySQL output?

To implement alternating row colors in a PHP and MySQL output, you can use a counter variable to keep track of the row number and apply different CSS classes based on whether the row number is even or odd. This can be achieved by using a ternary operator to determine the class to apply dynamically. 

```php
<?php
// Assuming you have fetched data from MySQL and stored it in $results array

$row_num = 0;
foreach($results as $row) {
    $row_class = ($row_num % 2 == 0) ? 'even-row' : 'odd-row';
    echo '<tr class="' . $row_class . '">';
    // Output your table data here
    echo '</tr>';
    $row_num++;
}
?>
```

In this code snippet, we iterate through the fetched data rows and apply the CSS class 'even-row' or 'odd-row' based on the row number. This will result in alternating row colors in the output table.
