If there's a limit on the length of something then you could always check the length of the thing beforehand, and if you don't want your code to exit, then don't use die().

function write($post,$myFile){
  if( strlen($myfile) > 260 ) {
    echo "Filename too long";
    return false;
  } else {
    if( ! $fh = fopen($myFile, 'a+') ) {
      echo "can't open file";
      return false;
    }
    fwrite($fh, $post);
    fclose($fh);
    return true;
  }
}
