关于数组函数

Question

遍历数组，获取cupID值后，重新生成新的数组．

Answer 1

最后的数组形式是array["$CupID"]["$Position"][..]

Answer 2

$arrTmp = array();
foreach($arrTest as $key=> $value)
{
$cupId = $value['CupID'];
$arrTmp[$cupId][] = $value;
}
print_r($arrTmp);结帖吧．

Answer 3

谢谢!
我的本来意思系,有无一个通用的函数,把一个二维的数组,生成多维的数组,
如array("0"=>array("Position"=>"1","CupID"=>"11","ID"=>""),"1"=>array("Position"=>"2","CupID"=>"11","ID"=>""),"2"=>array("Position"=>"31","CupID"=>"15","ID"=>""),"3"=>array("Position"=>"32","CupID"=>"15","ID"=>"")); 传入参数array("CupID","Position")=>可以生成 array["$CupID"]["$Position"][..]
传入参数array("CupID","Position","ID")=>可以生成 array["$CupID"]["$Position"]["$ID"][..]
