Convert New Lines to BR exclude PRE tags

[mridang_agarwal]

Hi.

 

Could someone tell me how I can use the nl2br function to convert newlines to BR tags in text but I would like to exclude all the text that is placed within PRE tags. I tried to find some examples online but couldn't.

 

Thanks guys.

Check out the user comments in nl2br(). Someone made such a function.

 

Orio.

Hi Orio,

 

I couldn't find any such thing. This seems to be a pretty small thing to accomplish but I don't know why I cant seem to find a decent code snippet to do this.

 

Anybody, any  help?

I think this is the example on php.net Orio was referring to... however I'm not 100% sure.

<?php

function nl2br_pre($string, $wrap = 40) {
  $string = nl2br($string);

  preg_match_all("/<pre[^>]*?>(.|\n)*?<\/pre>/", $string, $pre1);

  for ($x = 0; $x < count($pre1[0]); $x++) {
    $pre2[$x] = preg_replace("/\s*<br[^>]*?>\s*/", "", $pre1[0][$x]);
    $pre2[$x] = preg_replace("/([^\n]{".$wrap."})(?!<\/pre>)(?!\n)/", "$1\n", $pre2[$x]);
    $pre1[0][$x] = "/".preg_quote($pre1[0][$x], "/")."/";
  }

  return preg_replace($pre1[0], $pre2, $string);
}

?>
