optional parameters of "component"

[Zegnåt]

BTW: a return after the eval would be beneficial

What kind of return would you suggest? Something like this? (Modifying get_component() from the SVN.)

Code:

function get_component($id) {
    global $components;
    if (func_num_args() > 1) { $args = func_get_args(); array_shift($args); }
    if (!$components) {
         if (file_exists(GSDATAOTHERPATH.'components.xml')) {
            $data = getXML(GSDATAOTHERPATH.'components.xml');
            $components = $data->item;
        } else {
            $components = array();
        }
    }
    if (count($components) > 0) {
        foreach ($components as $component) {
            if ($id == $component->slug) {
                $eval = eval("?>" . strip_decode($component->value) . "<?php ");
            }
        }
    }
    return $eval===NULL||$eval!==FALSE;
}
