How Can I Preserve Line Breaks in Textarea Input?

Preserve Line Breaks from TextArea

When allowing users to input comments via a textarea, it can be frustrating when new lines entered are removed from the output. This article addresses this issue and provides two solutions to ensure line breaks are preserved.

Solution 1: PHP nl2br() Function

The PHP nl2br() function converts new line characters (n) to HTML line breaks (
).

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

Output:

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

Solution 2: HTML Preformatted Text

Enclosing the user's input within

tags prevents browsers from altering its formatting. This includes preserving line breaks.

<pre class="brush:php;toolbar:false">
This
is
a
string

Output:

This
is
a
string
