小白求指点：自定义函数内调用另外一个函数里的全局变量，该如何写

function marrbase(){<br />if(isset($_COOKIE["uname"]) && isset($_COOKIE["uid"])){<br />global $mbase;<br />$mbase_data = mysql_query("select * from dh_member where `id`=" . $_COOKIE["uid"] . " and `mck`=1");<br />if (!$mbase_data){die(mysql_error());exit();}<br />$mbase = mysql_fetch_array($mbase_data);<br />}<br />else{exit();}<br />}

<br />require_once("member.inc.php");<br />function supp(){<br />marrbase();<br />echo $mbase["email"]; exit();<br />}<br />
