数组中的数据相乘

Question

我将数据保留在Array中，我想将这些数据彼此相乘，但未成功。我找到了Array_product函数，但无法成功运行。您认为问题是什么？

$kuponlar = $_SESSION['kuponlar'];

$maclar = $kuponlar['maclar'];

我要相乘的数据：

echo array_product($maclar['oran']));

array_product在我想做时不起作用。是否有找不到该问题的建议？

Answer 1

您需要乘以数组中每个对象的属性oran：

$maclar = $kuponlar['maclar'];
$mul = 1;
foreach($maclar as $key => $value){
     $mul *=  $value->oran;    
}

Answer 2

在$ maclar数组中没有'oran'索引，首先应该创建一个'oran'数组，然后在该数组上使用array_product。 例如：

foreach($maclar as $key=>$object){
    $oran[] = $object->oran;
}

echo array_product($oran);
