MySQLI binding params using call_user_func_array

Question

Please see below my code. I am attempting to bind an array of paramenters to my prepared statement. I\'ve been looking around on the web and can see I have to use call_user_

Answer 1

Most of the above are not solutions without integrating the types along with the values before adding them to call_user_func_array(). This solution worked for me:

/* create a database connection */
$db = new mysqli($host, $user, $password, $db_name);

/* setup the sql, values, and types */
$sql="SELECT * FROM languages 
         WHERE language_code = ?
           AND charset = ?
         ORDER BY native_name";
$values = array($langCode, $charset);
$types = "ss";   

/* pass those variables to the execute() function defined below */
if ($rows = execute($sql, $values, $types))
{
   return $rows[0];
}

function execute($sql, $values='', $types='')
{
   /* prepare the sql before binding values and types */
   $stmt = $db->prepare($sql);

   /*combine the values and types into $inputArray */
   $inputArray[] = &$types;
   $j = count($values);
   for($i=0;$i<$j;$i++){
     $inputArray[] = &$values[$i];
   }
   /* add the combined values and types to call_user_func_array() for binding */
   call_user_func_array(array($stmt, 'bind_param'), $inputArray);
   $result = $stmt->execute();
   return $result;
}
