What is the potential issue with the PHP code that is causing all values to display in red?

The potential issue with the PHP code causing all values to display in red is that the CSS class responsible for coloring the text in red is being applied to all values. To solve this issue, we need to ensure that the CSS class is only applied to specific values that need to be displayed in red. This can be achieved by adding a conditional statement in the PHP code to check the value and apply the CSS class accordingly. 

<?php
// Sample PHP code snippet with conditional statement to apply CSS class only to specific values
foreach ($values as $value) {
    if ($value == 'red') {
        echo '<span class="red">' . $value . '</span>';
    } else {
        echo $value;
    }
}
?>
