get_component() optimization

[mvlcek]

To not use $GLOBALS:

Code:

$components = null;

function get_component($id) {
    global $components;
    if (!$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 == $component->slug) {
                eval("?>" . strip_decode($component->value) . "<?php ");
            }
        }
    }
}
