How do i enable line breaks in php?

Question

I am making a comments system in which i can accept user input with line breaks. I don't want to show the \n or \r thing Please help me with this

Answer 1

nl2br($string);

is fast and easy

Answer 2

They are enabled by default. If you are outputting the text to a web browser, make sure to use nl2br or the white-space attribute in CSS.

Answer 3

\n should do the trick.

if you are trying to output a textarea, then use nl2br();

also:-

If you are trying to format your HTML source, you should use the constant PHP_EOL. The main reason being that on windows machines the EOL is \r\n and on UNIX machines it is \n. With a properly installed LAMP set up just use PHP_EOL like so.

$html.="<p>This is my HTML</p>" . PHP_EOL;

Answer 4

using preg_replace

simply replace it

preg_replace('/\n/'," ",$str);

Answer 5

Line breaks will be stored just like any other character.

\n is an escape code that allows you to explicitly insert a line break into a string, but I don't think that it's relevant here.

The issue you're actually facing is that HTML does not impart any visual meaning to a line break. Line breaks within HTML code do not , under normal circumstances, equate to a line break on the screen.

One way to render a line break in HTML is to use a line break tag, or <br> .

In PHP, you can automatically convert line breaks to <br> with the nl2br function. Applying this to your comment text when you output it into HTML will enable you and other visitors to see the line break visually.
