I would like to mention fetching rows from SQL query using PDO:
<?php
$dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass);
// use the connection here
$sth = $dbh->query('SELECT * FROM countries');
// fetch all rows into array, by default PDO::FETCH_BOTH is used
$rows = $stm->fetchAll();
// iterate over array by index and by name
foreach($rows as $row) {
printf("$row[0] $row[1] $row[2]\n");
printf("$row['id'] $row['name'] $row['population']\n");
}
?>
