How can the presence of Carriage Return affect the handling of line breaks in PHP text fields?

When dealing with text fields in PHP, the presence of Carriage Return characters can affect the handling of line breaks. To solve this issue, you can use the PHP function `nl2br()` which converts newlines to HTML line breaks. This function will ensure that line breaks are displayed correctly in HTML output, regardless of the presence of Carriage Return characters.

// Example PHP code snippet to handle line breaks and Carriage Return characters
$text = "Hello\r\nWorld!";
echo nl2br($text);
