程序如下：<?phpfunction typelinks($idd){ //global dsql; $row = 12;$titlelen = 50;$dsql->SetQuery("Select * from `#@__flink` where ischeck>0 and typeid='$idd' order by sortrank asc");$dsql->Execute();$revalue = ""; for($i=1;$i<=$row;$i++){if($dbrow=$dsql->GetObject()){$wtitle = cn_substr($dbrow->webname,$titlelen);$revalue.= "<a href='".$dbrow->url."' target='_blank'>$wtitle</a>";if( $i % 6 == 0){$revalue.="<br>" ; }}if(!$dbrow) break;}return $revalue;}?> 函數調用：<?php echo typelinks(2) ?>報錯提示：Fatal error: Call to a member function on a non-object in 請高手幫忙解決下是什么問題？
