$hadShowProductId="";//已显示的productId

while($r=$empire->fetch($sql))

{

//$hadShowProductId.=$r[id].",";

if ( substr($hadShowProductId,-1,1) == "," ){ //去右 |

//$hadShowProductId = substr($hadShowProductId, 0, strlen($hadShowProductId)-1);//

}

//echo $hadShowProductId;

$array = explode(",",$hadShowProductId);

//print_r($array);

if (in_array($r[id],$array)){

continue;
