Each returned element is one record, with fields joined by
separator and a trailing newline.
<?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)');
$db->exec("INSERT INTO fruits VALUES (1, 'apple', 10), (2, 'banana', 20)");
$rows = $db->copyToArray('fruits');
var_export($rows);
?>
The above example will output:
array (
0 => '1 apple 10
',
1 => '2 banana 20
',
)
