code to destroy zend session gets executed although its not allowed by if else and switch case conditions - 


$getid = $this->getrequest()->getparam('id'); // 1 coming url $id_from_cart = 1;   if($getid != $id_from_cart) {         echo "unset session";         zend_session::namespaceunset('cart');  } else {       echo "dont unset";  }

when use $getid = 1 static value, working fine if use $this->getrequest()->getparam('id') value 1 although goes in else condition in both cases unsets session (code written in if condition). how possible, code destroy session has been written in if condition. have tried many things couldn't reach anywhere. suggestion great help. have tried switch case, in_array , if else.

try 

$getid = (int) $this->getrequest()->getparam('id');
