ecshop全局变量的设置和加载方式

$_CFG数组主要是放置一些系统参数，并且全站共享的数据，在使用的时候，ecshop里面常常以$GLOBALS['_CFG']全局变量的模式来处理。
ecshop 的$GLOBALS['_CFG']，主要是在includes/init.php中出现并且初始化，$_CFG = load_config();load_config()函数负责将参数取出来。includes\lib_common.php 文件中包含了这个ecshop函数。

function load_config()
{
$arr = array();
$data = read_static_cache('shop_config');
if ($data === false)
{
$sql = 'SELECT code, value FROM ' . $GLOBALS['ecs']->table('shop_config') . ' WHERE parent_id > 0';
$res = $GLOBALS['db']->getAll($sql);
foreach ($res AS $row)
{
$arr[$row['code']] = $row['value'];
}
