同一PHP文件，两个自定义函数之间的变量如何传递？拜托各位大神

同一PHP文件里面，两个自定义函数之间的变量如何传递？ 例如：function get_arts_list(){ $dsql; $dangqian=1; $max=50; $sql="select count(*) from #@__archives"; $rs=mysql_query($sql); $row=mysql_fetch_row($rs); $recount=intval($row[0]); $countpage=ceil($recount/$max); $dangqian=intval($_GET['page']); if($dangqian<1){ $dangqian=1; } if($dangqian>$max){ $dangqian=$max; } $dsql->SetQuery("Select * From `#@__archives` order by arcrank limit ".($dangqian-1)*$max.",".$max); $dsql->Execute(); function get_page_list(){ $pages=''; for($j=1;$j<$max;$j++){ if($dangqian==$j){ $pages .=$j; }else{ $pages .='<a href="content_list.php?page='.$j.'">'.$j.'</a>'; } } return $pages; } 两个函数都有$dangqian,怎样把上面的函数的$dangqian传给下面的函数？
