Example #1 Pdo\Pgsql::copyFromArray() example

Each element of rows is one record whose fields are joined by separator (a tab by default).

<?php
$db = new Pdo\Pgsql('pgsql:dbname=test host=localhost', $user, $pass);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->exec('CREATE TABLE fruits (id int, name text, qty int)');

$rows = [
    "1\tapple\t10",
    "2\tbanana\t20",
    "3\tcherry\t30",
];
$db->copyFromArray('fruits', $rows);

foreach ($db->query('SELECT * FROM fruits ORDER BY id') as $row) {
    echo "{$row['id']} {$row['name']} {$row['qty']}\n";
}
?>

Il precedente esempio visualizzerà:
