How to Preserve Line Breaks from Textarea Input in PHP and HTML?

Preserving Line Breaks from TextArea Input

When utilizing a textarea for user input, you may encounter the challenge of preserving line breaks during output. New lines entered in the textarea often disappear once displayed, leaving your text as a continuous stream.

Solution 1: PHP nl2br() Function

PHP provides the nl2br() function, which specifically addresses this issue. It converts new lines (rn) into HTML line breaks (
) within a given string.

For instance:

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

Output:

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

Solution 2:

 Tags

Another effective approach involves wrapping the user input within

tags. These tags essentially preserve the formatting and line breaks of the input, displaying it exactly as entered.
