Description:

working code on 4.3.3 version wont work on php 4.3.4-dev.

code at the bottom, i checked that $attach_content[1] is not empty also with healty base64 encoding.



Reproduce code:
---------------
  if($fp){
    $attach_content = fread($fp,filesize($attachment_file));
    fclose($fp);
    $attach_content = explode("EXPLODE_FROM_HERE",$attach_content);
    $attach_info = explode("~~",$attach_content[0]);
    $content_type = trim($attach_info[0]);
    $content_type = ereg_replace(";", "", $content_type);

    header("Content-transfer-encoding: binary\n");
    header("Content-Disposition: attachment; filename=$HTTP_GET_VARS[name]\n");

    if($attach_info[1]=="base64"){
      echo base64_decode($attach_content[1]);
    }
    if($attach_info[1]=="8bit"){
      echo imap_8bit($attach_content[1]);
    }
    if($attach_info[1]=="quoted-printable"){
      echo stripslashes(quoted_printable_decode($attach_content[1]));
    }
    if(empty($attach_info[1])){
      echo stripslashes($attach_content[1]);
    } 
  }
