There is an undocumented method "readOnly" in this class, as reported on https://bugs.php.net/bug.php?id=65216

This method can be used like this :

<?php

$db = new SQLite3(':memory:');
$db->exec('CREATE TABLE test (column);');

$stmt  = $db->prepare('SELECT column FROM test;');
var_dump($stmt->readOnly()); // -> true

$stmt  = $db->prepare('INSERT INTO test (42);');
var_dump($stmt->readOnly()); // -> false

?>
