Testing ORDER BY for Zend_Db_Select of ZF1

gistfile1.php

<?php
set_include_path('path/to/zf1/library');
require_once 'Zend/Db.php';

$db = Zend_Db::factory('Pdo_Mysql', array(
    'host'     => '127.0.0.1',
    'username' => '',
    'password' => '',
    'dbname'   => 'test'
));
$select = $db->select();
$select->from(array('p' => 'product'))->order('productId ASC');

$expected = 'SELECT `p`.* FROM `product` AS `p` ORDER BY `productId` ASC';
test($expected, $select);

$select = $db->select();
$select->from(array ('p' => 'product'))->order(array ('productId ASC', 'userId DESC'));
$expected = 'SELECT `p`.* FROM `product` AS `p` ORDER BY `productId` ASC, `userId` DESC';
test($expected, $select);

function test($expected, $select) {
    if ($expected === $select->assemble()) {
        printf ("OK: test passed\n");
    } else {
        printf ("FAIL: the select is not correct, %s\n", $select->assemble());
    }
}

Ok, really weird… your tests pass on our environments, even though we got issues there.

$ php gistfile1.php
OK: test passed
OK: test passed
