[PHP] How do I return the error

[Matthew Oatham]

Hi I have this function below - if it reurns false I want to also return the error so 
I can print it in my calling function. Can I do this?

Cheers

Matt

function fileUpload($file) {
  if ($file['type'] == "image/gif" || $file['type'] == "image/pjpeg"){ 
    if (@copy ($file['tmp_name'], "images/" . $file['name']))
      return true;
  }else { 
    return false;
  }
}
