Converting br into a new line for use in a text area

Question

If I have a variable    var1    Line 1 info blah blah  lt br   gt  Line 2 info blah blah     And a text area    lt textarea gt echo  var1 lt  textarea gt    How can I get the text area to display a new line instead of displaying the text on a single like with a  lt br   gt  in it   Edit  I have tried the following    lt textarea class  hobbieTalk  id  hobbieTalk  name  hobbieTalk  cols  35  rows  5  onchange  contentHandler  userInterests  this id this value 0   gt  lt  php   convert   SESSION  hobbieTalk     convert   str replace   lt br   gt      n    convert   echo  convert     gt  lt  textarea gt    However the text area still contains the br tags in the lines

i am use following construction to convert back nl2br

function br2nl( $input ) {
    return preg_replace('/<br\s?\/?>/ius', "\n", str_replace("\n","",str_replace("\r","", htmlspecialchars_decode($input))));
}

here i replaced \n and \r symbols from $input because nl2br dosen't remove them and this causes wrong output with \n\n or \r<br>.

The answer by  Mobilpadde is nice  But this is my solution with regex using preg replace which might be faster according to my tests   echo preg replace    lt br s     gt  i     r n    testing lt br  gt  lt br   gt  lt BR gt  lt br gt      function function one         preg replace    lt br s     gt  i     r n    testing lt br  gt  lt br   gt  lt BR gt  lt br gt        function function two         str ireplace    lt br   gt     lt br gt     lt br  gt       r n    testing lt br  gt  lt br   gt  lt BR gt  lt br gt        function benchmark          count   10000000       before   microtime true        for   i 0    i lt  count   i              function one                after   microtime true       echo   after- before   i     sec function one n           before   microtime true        for   i 0    i lt  count   i              function two                after   microtime true       echo   after- before   i     sec function two n     benchmark      Results   1 1471637010574E-6 sec function one  preg replace  1 6027762889862E-6 sec function two  str ireplace

Here is another approach   class orbisius custom string                  The reverse of nl2br  Handles  lt br  gt   lt br  gt   lt br   gt         usage  orbisius custom string  br2nl  Your buffer goes here                param str  buff         return str         author Slavi Marinov   http   orbisius com             public static function br2nl  buff                  buff   preg replace    lt br   s   gt  si     n    buff            buff   trim  buff            return  buff

EDIT  previous answer was backwards of what you wanted   Use str replace  replace  lt br gt  with  n  echo str replace   lt br gt      n    var1
