PHP PDO with foreach and fetch

Question

The following code:

Answer 1

foreach over a statement is just a syntax sugar for the regular one-way fetch() loop. If you want to loop over your data more than once, select it as a regular array first

$sql = "SELECT * FROM users";
$stm = $dbh->query($sql);
// here you go:
$users = $stm->fetchAll();

foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."
";
}
echo "
";
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."
";
}

Also quit that try..catch thing. Don't use it, but set the proper error reporting for PHP and PDO
