The problem I have is that it is giving me a warning in mysqli stating this:



Warning: mysqli_stmt::bind_param() [mysqli-stmt.bind-param]: Number of variables doesn't match number of parameters in prepared statement in ...on line 89

How can I get rid of the warning?
Code:
    $questionquery = "
    SELECT q.QuestionId, q.QuestionContent, o.OptionType, q.NoofAnswers, GROUP_CONCAT(an.Answer ORDER BY an.Answer SEPARATOR ' ') AS Answer, r.ReplyType, 
           q.QuestionMarks 
      FROM Answer an 
      INNER JOIN Question q ON q.AnswerId = an.AnswerId
      JOIN Reply r ON q.ReplyId = r.ReplyId 
      JOIN Option_Table o ON q.OptionId = o.OptionId 
    
    				 WHERE ";
    
    $i=0;
    foreach ($terms as $each) {     
    	$i++;         
    	
    	if ($i == 1){         
    		$questionquery .= "q.QuestionContent LIKE ? ";     
    		} else {         
    			$questionquery .= "OR q.QuestionContent LIKE ? ";    
    			 } 
    			 }  
    			 
    			 $questionquery .= "GROUP BY q.QuestionId, q.SessionId ORDER BY "; $i = 0; foreach ($terms as $each) {     
    				 $i++;      
    				 
    	if ($i != 1)         
    	$questionquery .= "+";     
    	$questionquery .= "IF(q.QuestionContent LIKE ? ,1,0)"; 
    	} 
    	
    	$questionquery .= " DESC "; 
    
    	$stmt=$mysqli->prepare($questionquery);      
     	$stmt->bind_param('s', $each = '%' . $each . '%');
    	$stmt->execute(); 
    	$stmt->bind_result($dbQuestionId,$dbQuestionContent,$dbOptionType,$dbNoofAnswers,$dbAnswer,$dbReplyType,$dbQuestionMarks); 
    	$questionnum = $stmt->num_rows();
