How can PHP developers prevent unexpected changes in formatting when saving and displaying text from arrays?

When saving and displaying text from arrays in PHP, developers can prevent unexpected changes in formatting by using the `htmlspecialchars()` function to escape special characters before saving the text to the array. This ensures that the text is stored as-is and will be displayed correctly when retrieved from the array. 

// Save text to array with htmlspecialchars() to prevent unexpected formatting changes
$text = "This is <b>bold</b> text";
$array['text'] = htmlspecialchars($text);

// Display text from array without unexpected formatting changes
echo $array['text'];
