What’s going on in this code? Specifically,

$  title = trim($  title); 

Because it looks like $ title is being assigned a value, then the entire value is being trimmed. It doesn’t make much sense to me.

$  title = $  address->getDiscountDescription();  $  description = $  address->getDiscountDescriptionArray(); //array(); foreach($  this->_cards as $  _id => $  value){     $  description[$  _id] = 'Gift Cards '.= $  value['card_code']; }  $  description[$  quote->getRuleId()] = $  quote->getCouponCode();  $  codes  = implode(",", $  this->_cardCodes); if(strlen($  codes) && !strpos($  title, 'Cards')){     $  title .= Mage::helper('giftcards')->__(' Gift Cards %s', $  codes); }  $  title = trim($  title);  $  address->setDiscountDescription($  title); $  address->setDiscountDescriptionArray($  description);
