Are there any specific PHP functions or methods that can be used to change the appearance of a specific row in an HTML table based on certain conditions?

To change the appearance of a specific row in an HTML table based on certain conditions, you can use PHP to dynamically add a CSS class to the row based on the condition. This can be achieved by checking the condition while looping through the data to populate the table rows, and adding the class to the row if the condition is met. 

```php
<?php
// Sample data for the table
$data = [
    ['name' => 'John', 'age' => 25],
    ['name' => 'Jane', 'age' => 30],
    ['name' => 'Mike', 'age' => 20]
];

echo '<table>';
foreach ($data as $row) {
    $class = ($row['age'] < 25) ? 'highlight' : ''; // Add 'highlight' class if age is less than 25
    echo '<tr class="' . $class . '">';
    echo '<td>' . $row['name'] . '</td>';
    echo '<td>' . $row['age'] . '</td>';
    echo '</tr>';
}
echo '</table>';
?>
```

In this code snippet, we loop through the data array and check if the age is less than 25. If the condition is met, we add a 'highlight' class to the table row. You can then define the CSS styles for the 'highlight' class in your stylesheet to change the appearance of the row as needed.
