OOP selecting data mysql - php

Question

I'm new to OOP and just trying to migrate from mysql_, but I'm running into some issues while migrating.
$konek = new PDO('mysql:host=localhost;dbname=mydatabase', root, root);$hasil = $konek->query("SELECT * FROM `tabel`");
while ($data = $hasil->fetch_object()) {
echo '<td>'.$data->something.'</td>';}
It doesn't work or show an error, but when I replace the first line with mysqli it works:
konek = new mysqli('localhost','root','root','mydatabase');
Any help would be really appreciated.

Answer 1

I assume in your code, it is coded as string: (or is root defined?)
$konek = new PDO('mysql:host=localhost;dbname=mydatabase', root, root);
Clearly, in your example, if it's a type change it to:
$konek = new PDO('mysql:host=localhost;dbname=mydatabase', 'root', 'root', array(PDO::ATTR_ERRMODE => PDO::ERRMODE_WARNING));
Refactor your code into this:
error_reporting(E_ALL);
ini_set("display_errors", 1);
try {
$konek = new PDO('mysql:host=localhost;dbname=mydatabase', 'root', 'root', array(PDO::ATTR_ERRMODE => PDO::ERRMODE_WARNING));
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
$hasil = $konek->query("SELECT * FROM `tabel`");
echo '<table>';
while ($row = $hasil->fetch(PDO::FETCH_OBJ)) {
echo '<tr>';
echo '<td>' . $row->column_name . '</td>';
echo '</tr>';
}
echo '</table>';

Answer 2

1)User name and password should be quoted string
2) use try catch
3) use prepare and execute the query
4) then fetch
try like this:
try {
$konek = new PDO('mysql:host=localhost;dbname=mydatabase', 'root', 'root');
$konek->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
die( 'ERROR: ' . $e->getMessage());
}
try {
$hasil = $konek->prepare("SELECT * FROM `tabel`");
$hasil->execute();
while ($data = $hasil->fetch(PDO::FETCH_OBJ)) {
echo '<td>'.$data->something.'</td>';
}
}
catch(PDOException $e) {
die( 'ERROR: ' . $e->getMessage());
}

Answer 3

Please provide an error message it echoes.
MY best guess:
http://www.php.net/manual/en/pdostatement.fetchall.php
Try replacing
while ($data = $hasil->fetch_object()) {
echo '<td>'.$data->something.'</td>';}
with
while ($data = $hasil->fetchAll()) {
echo '<td>'.$data->something.'</td>';}
