$sql = "SELECT c.cat_id, c.cat_title, c.cat_order
FROM " . CATEGORIES_TABLE . " c
ORDER BY c.cat_order";
if( !($result = $db->sql_query($sql)) )
{
message_die(GENERAL_ERROR, 'Could not query categories list', '', __LINE__, __FILE__, $sql);
}


$category_rows = array();
if ($db->sql_numrows($result) > 0) {
while( $category_rows[] = $db->sql_fetchrow($result) )
{
$cat_id = intval($category_rows['cat_id']);
$content .=$cat_id;
}
}
可是为什么读出来的id全是0呢？
