这个是已有的函数：
function checkad($sortsid)
{
global $db,$table_sorts;
//查询设备信息
$sql = "select supsortid from $table_sorts where sortid=$sortsid";
$query = $db->query($sql);
$supsortid = $db->result($query,0);
print "supid=".$supsortid." <br>";
if($supsortid==0)
{
print "sortsid=".$sortsid." <br>";
$temps = $sortsid;
return $sortsid;
}
elseif($supsortid!=0)
{
print "123456 <br/>";
checkad($supsortid);
print "456798";
print "1111111111111111111111"." <br>";
}
//return $temps;
}
这个是调用方法的代码：
$tempid = $_GET['sortid'];
$eqads=checkad($tempid);
print "123456=".$eqads;
if($eqads!='')
{
//根据编号查询所有的广告信息
$sql = "select * from $table_pic where class2=2 and class3=$eqads";
$query = $db->query($sql);
