Answered Different usage of $modx->resource... in snippets and in plugins?

<?php
$arg_list = func_get_args();
$output = array();
foreach($arg_list as $args) {
    if (is_array($args)) {
        foreach($args as $key => $val) {
            $value = 'OBJECT';
            try {
                //don't print the object, especially $resource/$xpdo object coz too big
                if (!is_object($val)) {
                    if (is_array($val)) {
                        $value = "(Array)". serialize($val);
                    } else {
                        $value = $val;
                    }
                }
            } catch (Exception $e) {
                $value = "(error)" . $e->getMessage();
            }
            $output[] = "[$key]: $value";
        }
    }
}
$text = "\n--------\nEVENT: " .$modx->event->name;
foreach($output as $val) {
    $text .= "\n$val";
}
$text .= "\n--------";
$modx->log(modX::LOG_LEVEL_ERROR, $text);
