How to remove line breaks in email?

Question

PHP

Hello. There was a problem with extra line breaks when receiving emails. The code is something like this:

function Send() {
  $header = '...';
  $body = $this->CreateBody();
  $result = $this->MailSend($header, $body);
  return $result;
}

function CreateBody() {
  $result = "";
  $result .= $this->EncodeString($this->Body, $this->Encoding);
  return $result;
}

function EncodeString ($str, $encoding = "base64") {
  $encoded = $this->FixEOL($str);
  if (substr($encoded, -(strlen($this->LE))) != $this->LE)
  $encoded .= $this->LE;
  return $encoded;
}

function FixEOL($str) {
  $str = str_replace("\r\n", "\n", $str);
  $str = str_replace("\r", "\n", $str);
  $str = str_replace("\n", $this->LE, $str);
  return $str;
}

function MailSend($header, $body) {
  $to = '...';
  $sbj = '...';
  $rt = @mail($to, $sbj, $body, $header);
  return true;
}

As a result, $body is formed correctly just before sending, but in the letter it comes with extra hyphens that distort the text (screenshot from the properties of the letter in Yandex Mail). Tell me, please, in which direction to dig to correct the text?

Most likely the problem is here:

if (substr($encoded, -(strlen($this->LE))) != $this->LE)
  $encoded .= $this->LE;

I really don’t see where your str gets into encoded, but if, for example, the line terminator is LF in str (which is more than likely), and your LE is CRLF, then the result will be LFCRLF. That's right - throw out any CR and LF terminators at the end of the line and add CRLF.
