Question

我试图从以下

获取stocklevels的计数和值

Array ( [barcodes] => Array ( [barcode] => 10011010009 ) [basePrice] => 25.00 [customFields] => Array ( ) [description] => CBC-CBCJSW [discontinued] => false [PLU] => CBC Boy's Shirt 20 [priceLevels] => Array ( ) [primaryCategory] => CBC- Boys Shirts [productLineName] => CBC Boy's Shirt 20 [promptPOSOperatorForPrice] => false [sellByWeightOption] => false [stock] => Array ( [stockLevel] => Array ( [0] => Array ( [outletExportCode] => Level1 [stockCount] => 500.000000 ) [1] => Array ( [outletExportCode] => Level2 [stockCount] => 1000.000000 ) ) ) [taxes] => Array ( [taxName] => GST ) )

我尝试过以下操作，即使数组中有2个级别，我也会一直得1：

 count($ra['stock']['stockLevel']['stockCount']);
 count($ra['stock']['stockLevel']);

另外，我试图循环搜索结果以获得库存，但它似乎不起作用：

    $stockLevelArr[] = $ra['stock'];
        $totalStock = 0;

    for($i=0;$i<count($stockLevelArr);$i++){

        echo $ra['productLineName'] . ' - Stock outside IF: ' . (int) $stockLevelArr[$i]['stockLevel']['stockCount'];
        echo '<br>';

        if (isset($stockLevelArr[$i]['stockLevel']['stockCount'])) {
            $totalStock = $totalStock + $stockLevelArr[$i]['stockLevel']['stockCount'];
        }
    }

    echo 'Stock count: ' . $totalStock;
    echo '<br>';

var dump

array(13) { ["barcodes"]=> array(1) { ["barcode"]=> string(11) "10011010009" } ["basePrice"]=> string(5) "25.00" ["customFields"]=> array(0) { } ["description"]=> string(10) "CBC-CBCJSW" ["discontinued"]=> string(5) "false" ["PLU"]=> string(18) "CBC Boy's Shirt 20" ["priceLevels"]=> array(0) { } ["primaryCategory"]=> string(16) "CBC- Boys Shirts" ["productLineName"]=> string(18) "CBC Boy's Shirt 20" ["promptPOSOperatorForPrice"]=> string(5) "false" ["sellByWeightOption"]=> string(5) "false" ["stock"]=> array(1) { ["stockLevel"]=> array(2) { [0]=> array(2) { ["outletExportCode"]=> string(13) "Tara Uniforms" ["stockCount"]=> string(10) "500.000000" } [1]=> array(2) { ["outletExportCode"]=> string(3) "CBC" ["stockCount"]=> string(11) "1000.000000" } } } ["taxes"]=> array(1) { ["taxName"]=> string(3) "GST" } }

我将不胜感激。

更新：以下工作。感谢大家的回复和帮助。

    $totalStock = 0;

    $times_found = 0;
    $stock = $ra['stock'];
    foreach($stock['stockLevel'] as $stock_level) {
        if(isset($stock_level['stockCount'])) {
            $times_found++;
            $totalStock = $totalStock + $stock_level['stockCount'];
        }
    }

Answer 1

我假设你想知道数组中stockCount多少次？如果是这样，我将使用数组循环遍历数组的每个索引，并在每次找到它时递增一个变量。例如：

$times_found = 0;
foreach($ra['stock'] as $stock) {
    foreach($stock['stockLevel'] as $stock_level) {
        if(isset($stock_level['stockCount'])) {
            $times_found++;
        }
    }
}

Answer 2

您应该计算递归以获取计数中的所有键：

count($ra, COUNT_RECURSIVE);

另请参阅php手册https://www.php.net/manual/en/function.count.php

我认为你应该将你的for循环更改为：

<?php

$totalStock = 0;


foreach ($ra['stock'] as $stock) {

   echo $ra['productLineName'] . ' - Stock outside IF: ' . (int) $stock['stockLevel']['stockCount'];
   echo '<br>';

   if (isset($stock['stockLevel']['stockCount'])) {
       $totalStock = $totalStock + $stock['stockLevel']['stockCount'];
   }
}

echo 'Stock count: ' . $totalStock;
echo '<br>';

而不是for循环，不知道你为什么使用它，你最好在这个例子中使用foreach。

PHP无法获取数组子元素的数量
