Add \n every 80 charechter in a string

[lowspeed]

Hi there,

I'm trying to use mail() to send a form with a text box... now the problem is if the textbox has a string longer then a certin length mail() truncates it.

So i need a method to add \n to the string every lets say 80 chars.

Help would be appriciated!

function newlineString($string){
  for($i=1;$i<strlen($string);$i++){
    $newstring .= $string[$i-1];
    if($i > 1 && $i % 80 == 0){
        $newstring .= "\n";
    }
  }
  return $newstring;
}
echo newlineString($string);

Something like this I think.

I wanna be in the thread too.

function charabunga($string, $start, $length, $char)
{
  $start=$start+$length;
  if($start<strlen($string)) {
    $string=substr($string, 0, $start).$char.substr($string, $start));
    return addCharr($string, $start, $length, $char);
  } else {
    if(strlen($string)==0) {
      return false;
    } else {
      return $string;
    }
  }
}

Use wordwrap though, mine's effectively just going to be a slower implementation unless of course you have a perchant for funtions with cool names. With mine you could write this.

if($ninja_turtle=charabunga($string)) {
  die('shredder');
}

😃 I'm sure that sounds a lot cooler in my head than it really is.

Damnit, I looked for a function that might do it too 🙂
