Operating system: Red Hat 4.0.1-5
PHP version: 4.4.1
PHP Bug Type: Variables related
Bug description: erroneous notice concerning return by reference
Description:
------------
When returning a newly created object, PHP throws up a notice (sounds like
warning) like "Only variable references should be returned by reference".
This happens in PEAR::Mail_Mime, location Mail/mime.php on line 320. I
don't think this is a Mail_Mime error.
The one on line 593 is a Mail_Mime error, though. It returns the value of
a function call, and that function called wasn't declared with
return-by-reference.
Even if this isn't a bug by your standards (and by the PHP manual written
by you guys), please do consider it a feature request? I upgraded from
4.4.0 just because I thought you guys fixed this issue.
I'm using Mail 1.1.9 and Mail_Mime 1.3.1.
My PHP config:
--enable-safe-mode
--disable-short-tags
--with-apxs=myapxs
--enable-discard-path
--enable-fastcgi
--with-mysql
Reproduce code:
---------------
function &_addTextPart(&$obj, $text)
{
$params['content_type'] = 'text/plain';
$params['encoding'] = $this->_build_params['text_encoding'];
$params['charset'] = $this->_build_params['text_charset'];
if (is_object($obj)) {
return $obj->addSubpart($text, $params);
} else {
return new Mail_mimePart($text, $params); // Offending line!!
}
}
function &headers($xtra_headers = null)
{
// Content-Type header should already be present,
// So just add mime version header
$headers['MIME-Version'] = '1.0';
if (isset($xtra_headers)) {
$headers = array_merge($headers, $xtra_headers);
}
$this->_headers = array_merge($headers, $this->_headers);
return $this->_encodeHeaders($this->_headers); // Offending line!!
}
Expected result:
----------------
There shouldn't be a notice when we return a new instantiation of an
object through a function declared to return by-reference.
