How can PHP developers prevent errors related to different line break characters in textarea inputs?

When dealing with textarea inputs in PHP, developers can prevent errors related to different line break characters by normalizing the line breaks to a consistent format. This can be achieved by using the PHP function `str_replace()` to replace all types of line breaks (e.g., \r\n, \r, \n) with a single consistent line break character (e.g., \n).

// Normalize line breaks in textarea input
$text = $_POST['textarea_input'];
$text = str_replace(array("\r\n", "\r"), "\n", $text);
