php syntax, the operator =&

Question

I have a question about the PHP syntax.Below is the php code:

$err = $campaign =& $this->_setCampaign($mission['campaign_id'])

what does the "=&" mean? I had googled but since google doesn't support for searching these marks.Is it something about the assign by reference issue?

That's a reference operator.

Yes, it's assignment by reference. Read more in the manual.
