stmt get_result another way - php

Question

An example of one of my queries...
public function db_query_select($query, $params, $param_types){
$dbc = $this->dbConnect();
if($stmt = $dbc->prepare($query)){
//prepared.
//move the types to the front of the param array
array_unshift($params, $param_types);
//call the bind param function with the parameters passed in by reference
//bind_param only allows by reference.
call_user_func_array(array($stmt, "bind_param"), $this->paramsToRefs($params));
//binded.
//attempt to execute the sql statement.
if ($stmt->execute()){
$result = $stmt->get_result();
$stmt->close();
$dbc->close();
return $result;
}
}
//must have failed...
return NULL;
}
how can I change stmt get_result(); to something that is accepted by shared servers/hosts without the native driver... mysqlnd.
Anyone know? without changing all of my functions that use this database function.
Thanks.
UPDATED:::: Thanks to #your common sense, See Answer.
I believe this is what I was after. Hope it helps anyone that was having the same problem as myself. PDO vs MySQLi, seems simpler... no user call func or anything like that.
DB HANDLER:
private function dbConnect(){
$config = parse_ini_file($_SERVER['DOCUMENT_ROOT'].'/NTConfig.ini');
try {
$dbc = new PDO('mysql:host='.$config['DB_HOST'].';dbname='.$config['DB_DATABASE'].'', $config['DB_USER'], $config['DB_PASSWORD']);
$dbc->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
exit;
}
return $dbc;
}
public function db_query_select($query, $params){
$dbc = $this->dbConnect();
if($stmt = $dbc->prepare($query)){
//prepared.
//attempt to execute the sql statement.
if ($stmt->execute($params)){
$result = $stmt->fetch(PDO::FETCH_ASSOC);
print_r($result);
//$stmt->close();
//$dbc->close();
return $result;
}
}
//must have failed...
return NULL;
}
Outside the DBHANDLER
$query = "SELECT error_desc FROM nt_errors WHERE error_code = :ERROR_CODE LIMIT 1";
//array: holds parameters for the query.
$params = array(
':ERROR_CODE' => $code
);
$result = $db->db_query_select($query, $params);
if ($result == NULL){
$errorText = 'ERROR: Failed to retrieve error';
}
else{
//var_dump($result);
$errorText = $result['error_desc'];

PDO is not only much more user friendly than mysqli but also doesn't have any of such a nasty drawbacks. So I strongly suggest to use PDO instead of mysqli.
With DO, the function you're after should be as simple as this
function run($sql, $args = NULL)
{
$pdo = ...;//your means of getting the connection variable
$stmt = $pdo->prepare($sql);
$stmt->execute($args);
return $stmt;
}
After gettin the function's result, you can chain a fetch method to its call, fetchColumn() in your case.
Given your code is mostly procedural, let me suggest you a very simple PDO wrapper I wrote. So the full code would be:
$sql = "SELECT error_desc FROM nt_errors WHERE error_code = ?";
$errorText = DB::run($sql,[$code])->fetchColumn();
if (!$errorText){
$errorText = 'ERROR: Failed to retrieve error';
}
Here DB class is a better replacement of your dbConnect() function, and run() method is a replacement for db_query_select() that actually can be used for any query type, including insert, update or anything.
