How Can I Preserve Line Breaks in Text Area Output?

Preserving Line Breaks in Text Area Output

When working with text areas, it is often desirable to preserve line breaks when the entered text is displayed. However, by default, line breaks are lost during output. Here are two effective solutions to overcome this issue:

1. Utilizing the nl2br() Function:

The nl2br() function converts new line characters ("n") into HTML line break tags (
). By processing the text through this function, you can ensure that line breaks are maintained when displayed.

For example:

$text = "This\r\nis\n\ra\nstring\r";
echo nl2br($text);

// Output:
This<br />
is<br />
a<br />
string<br />

2. Encapsulating Text in

Tags:

Wrapping the input text within

tags preserves its formatting, including line breaks. This approach is particularly useful when you want to display raw text or maintain its original structure.
