The Shortcode Callback plugin allows you to use a [callback] shortcode to execute arbitrary PHP code wherever the shortcode is used.

Usage

Execute someFunction() and insert whatever it returns with the following shortcode:

[callback function="someFunction"]

Example shortcode to include a PHP file (the path is relative to WordPress' ABSPATH), then insert the results of someFunction() where you used the shortcode:

[callback include="custom/filetoinclude.php" function="someFunction"]

Shortcode example that includes a PHP file (the path is relative to WordPress' ABSPATH), then passes a paramter to someFunction() and returns the results where you used the shortcode:

[callback function="someFunction" include="custom/filetoinclude.php" param="something"]

The format to call a class/method with the shortcode is exactly the same as above, except you specify the class::method in the "function" attribute of the shortcode.

[callback function="someClass::someFunction" include="custom/filetoinclude.php" param="something"]

There is an example (with PHP code) over here.

class DigitalPointElectricity
{
    public static function total_output($timeframe)
    {
        $totals = $GLOBALS['memcache']->get('shawnhogan-pv-total');

        if ($timeframe == 'total')
        {
            return $totals->Items[2]->TotalYield;
        }
        elseif ($timeframe == 'daily')
        {
            return $totals->Items[1]->DailyYield;
        }
    }
}
