Answer 1

从问题中你不需要理解你需要什么，但根据图像，这就是你想要的：

  $sellbuy = array("b","s","b","b","b","s","b","s","s");
  $amount = array("10","10","1","1","1","3","5","2","3");

$trades=0;
$i=0;
$tamount=0;
$a=0;
foreach($sellbuy as $saction){
echo $i.") ".getTotalTrades($saction,$amount[$i],$trades,$tamount)."<br />";
$i++;
}

function getTotalTrades($faction,$famount,&$trades,&$tamount){
    if($faction=="s"){
       if($trades==0 || $trades==1){
        $toreturn = "1, in amount of: ".$famount."<br />";
        }else{
        $toreturn = $trades.", in amounts of: ".$tamount."<br />";
        }
        $trades=0;
        $tamount = 0;
        return $toreturn;
    }else{  //the user is buying
    $trades++;
    $tamount = $famount+$tamount;
return "buy only";
    }
}

当然，您可以根据需要进行更改。

祝你好运！
