It turned out to be an easy fix once I figured out the problem, though; I just had to change the ownership of /var/www/cgi-bin and it’s contents so that the apache user could execute cgi_wrapper.

Here’s what was turning up in the error logs:

Apache vhost error_log

[warn] [client xx.xx.xx.xx] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[error] [client xx.xx.xx.xx] Premature end of script headers: index.php

/var/log/httpd/error_log

suexec policy violation: see suexec log for more details

/var/log/httpd/suexec_log

uid: (10001/username) gid: (505/505) cmd: cgi_wrapper

/var/log/httpd/suexec.log

target uid/gid (10001/505) mismatch with directory (0/0) or program (0/0)
uid: (10001/username) gid: (505/505) cmd: cgi_wrapper

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
);

function getBlipThumbnail($embedURL, $parse = '')

	}
	else
	{
		$urlStart = strpos($videoRSS, 'media:thumbnail url="');

		if($urlStart !== false)
		{
			$substrLength = strpos($videoRSS, '"/>', $urlStart) - $urlStart;
			$thumbnailURL = substr($videoRSS, $urlStart + 21, $substrLength - 21);
		}
		else

	}

	return $thumbnailURL;
}

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().
