Таблица news в БД test как видно имеется и доступ к ней есть:
<?php
$dsn = 'mysql:host=127.0.0.1;dbname=test';
$dbh = new PDO($dsn, 'root', '');
$sth = $dbh->prepare('SELECT * FROM news');
$sth->execute();
$data = $sth->fetchAll();
var_dump($data);
Реузльтат:
array(3) { [0]=> array(8) { ["id"]=> string(1) "1" [0]=> string(1) "1" ["title"]=> string(50) "Большие слоны идут на север" [1]=> string(50) "Большие слоны идут на север" ["lead"]=> string(0) "" [2]=> string(0) "" ["author_id"]=> string(1) "1" [3]=> string(1) "1" } [1]=> array(8) { ["id"]=> string(1) "2" [0]=> string(1) "2" ["title"]=> string(58) "Метеорит упал рядом с человеком" [1]=> string(58) "Метеорит упал рядом с чело-веком" ["lead"]=> string(0) "" [2]=> string(0) "" ["author_id"]=> string(1) "2" [3]=> string(1) "2" } [2]=> array(8) { ["id"]=> string(1) "3" [0]=> string(1) "3" ["title"]=> string(65) "Экономика оставляет желать лучшего" [1]=> string(65) "Экономика оставляет желать лучшего" ["lead"]=> string(0) "" [2]=> string(0) "" ["author_id"]=> string(1) "3" [3]=> string(1) "3" } }
