Following on from the Pdo\Pgsql::lobCreate()
example, this code snippet retrieves the large object from
the database and outputs it to the browser.
<?php
$db = new Pdo\Pgsql('pgsql:dbname=test host=localhost', $user, $pass);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->beginTransaction();
$stmt = $db->prepare("SELECT oid FROM BLOBS WHERE ident = ?");
$stmt->execute([$some_id]);
$stmt->bindColumn('oid', $oid, PDO::PARAM_STR);
$stmt->fetch(PDO::FETCH_BOUND);
$stream = $db->lobOpen($oid, 'r');
header("Content-type: application/octet-stream");
fpassthru($stream);
?>
