Another option is the SimpleTest for WordPress plugin, which uses SimpleTest instead of PHPUnit, doesn’t require installing a PEAR package, and lets you run both unit and  integration tests.

Either way, you can use PHP’s ReflectionClass to test private and protected methods, although purists will tell you that’s not proper.

Parse error: parse error, unexpected T_VARIABLE in /path/to/your/directory/wp-includes/load.php on line 566

It’s because the clone keyword doesn’t exist in PHP4.

That creates a new problem, though, if the table name is stored in a chained property. PHP will only parse out the first level, so it’ll come out as something like “database_name.Object ID #3->column_name”. To fix that, you need to wrap the entire chain in curly braces, this like:

$resultRows = $wpdb->get_results(
  $wpdb->prepare(
    "SELECT result_id FROM `{$this->cfs->resultsTable}` WHERE user_id = %d",
    $user_id
  ), ARRAY_A
);

Instead of displaying the errors, you can configure PHP to log them and then use the logs for debugging. For a Linux environment, you’ll need to create a file named vhost.conf inside the domain’s conf directory, /var/www/vhosts/domain.name/conf.

<Directory /var/www/vhosts/domain.name>
  php_value error_log /var/www/vhosts/domain.name/statistics/logs/php-errors.log
  php_flag display_errors off
  php_value error_reporting 6143
  php_flag log_errors on
</Directory>

Then create the file and assign it the right permissions

  cd /var/www/vhosts/domain.name/statistics/logs/
  touch php-errors.log
  chown apache php-errors.log

And the last thing is to tell Apache to reread the updated conf file

  /usr/local/psa/admin/sbin/websrvmng -a

There are a lot of hacks available, but all of the ones I’ve seen only work in specific circumstances. The only comprehensive solution I found to do the sorting in MySQL is Drupal’s natsort module. You don’t need to be running Drupal to use it, just issue the queries that create the function and it’s dependencies, and you can then call it in your regular queries. But, it requires MySQL 5, so if you’re working on an older server and your data doesn’t work with one of the hacks, then you’ll probably just have to do the natural sorting in your scripting language, using something like PHP’s natsort().

I came back a few days later and skimmed through the code again and eventually figured out that it was using the wp_options table, but only one field. All of the global settings, form settings and form data are stored in a single field, in a serialized format that only an MIT grad on crack could parse by hand.

I added a post to their forums to help anyone else in my position, and also to mention that maybe their approach wasn’t the most intuitive, organized or standard. After a couple of days I checked back to see if anyone had left any comments on it, but it was gone. Lame… How petty and insecure do you have to be to censor criticism?

So anyway, in the end all you really need to do is use get_option() to get an associative array of all of the data.

$cforms = get_option('cforms_settings'); // get the data
echo '<pre>'. print_r($cforms, true) .'</pre>'; // output in readable format

Update: Ok, so this is really more a case of me being behind the curve on WP plugin development. Using serialized options is the standard now.

After you’ve got the module working working you can just put the database server’s hostname and port in the db parameter of oci_connect(), rather than messing with a tnsnames.ora file.

oci_connect('username', 'password', '127.0.0.1:1521/dbname');

Update: The Underground PHP and Oracle Manual has a lot of information on installation, and also a good section on tuning. oci_pconnect() can be used to create a persistent connection to the database server, rather than creating a new one during each script instance.
