最大的foreach数组值？ [英] foreach max array value?

问题描述

我是相当新的PHP和我有问题循环。我有一个foreach循环，

I'm fairly new to php and i have problem with loops. I have a foreach loop,

foreach ($contents as $g => $f)
{
  p($f);
}

这给一些阵列，这取决于我有多少内容有。目前我有2个，

which gives some arrays, depending on how many contents i have. currently i have 2,

Array
(
    [quantity] => 1
    [discount] => 1
    [discount_id] => 0
    [id] => 1506
    [cat_id] => 160
    [price] => 89
    [title] => კაბა
)

Array
(
    [quantity] => 1
    [discount] => 1
    [discount_id] => 0
    [id] => 1561
    [cat_id] => 160
    [price] => 79
    [title] => ზედა
)

我的目标是挽救它有它最大的价格为不同的变量数组。我有点停留在如何做到这一点，我设法找到最高价与 MAX（）函数像这样

foreach ($contents as $g => $f)
{

    $priceprod[] = $f['price'];
    $maxprice = max($priceprod);
   p($maxprice);
}

但我仍然不明白我也应该找出其中的数组是最高价。任何建议，将AP preciated

but i still dont get how i'm supposed to find out in which array is the max price. any suggestions would be appreciated

推荐答案

您应该存储密钥，以及让你可以在循环之后看它：

You should store the keys as well so that you can look it up after the loop:

$priceprod = array();

foreach ($contents as $g => $f)
{
  // use the key $g in the $priceprod array
  $priceprod[$g] = $f['price'];
}

// get the highest price
$maxprice = max($priceprod);

// find the key of the product with the highest price
$product_key = array_search($maxprice, $priceprod);

$product_with_highest_price = $contents[$product_key];

请注意，如果有多个产品与同价位的结果将是不可靠的。

Note that the results will be unreliable if there are multiple products with the same price.
