How can PHP developers effectively troubleshoot issues with incorrect data output, such as displaying array contents within HTML tags, as shown in the forum thread?

To troubleshoot issues with incorrect data output, PHP developers can ensure that array contents are properly displayed within HTML tags by using PHP's foreach loop to iterate through the array and echo the values within the desired HTML tags. 

<?php
$colors = array("red", "green", "blue");

echo "<ul>";
foreach ($colors as $color) {
    echo "<li>" . $color . "</li>";
}
echo "</ul>";
?>
