ZF-12525: Incorrect parameter in Zend\Db\Adapter\Driver\Mysqli\Statement::prepare
Following bug applies to ZF2 (2.2) - could not find a place where to file this so here it goes.
In the prepare method of Zend\Db\Adapter\Driver\Mysqli\Statement the following line of code:
$this->resource = $this->mysqli->prepare($this->sql);
should actually be:
$this->resource = $this->mysqli->prepare($sql);
