從給定數組中獲取值

Question

我有一個像這樣存儲在$ result中的數組

$result=$array

通過使用echo $ result我得到以下數組

Array
(
    [success] => 1
    [product] => Array
        (
            [id] => 83

我可以像這樣單獨獲取結果

$finalid = $array['product']['id']; 
echo $finalid;

但希望使用for循環獲取每個數據，甚至是最內部的數據。 為此我試過這個

$c=count($result);
    for ( $i=0; $i < $c; $i++)
    { 
       echo $array[$i]['id'];
       echo $array[$i]['images'][0];
       echo $array[$i]['options'][0]['product_option_id'];
       echo $array[$i]['images'][0]['option_value'][0]['product_option_value_id'];
       echo $array[$i]['images'][0]['option_value'][1]['product_option_value_id'];
    } 

但它沒有顯示任何結果，任何人都可以告訴它是如何做到的

Answer 1

Use:
$products = $result['product'];
foreach ( $products as $product )
{ 
   echo $product['id'];
   echo $product['images'][0];
   echo $product['options'][0]['product_option_id'];
   echo $product['images'][0]['option_value'][0]['product_option_value_id'];
   echo $product['images'][0]['option_value'][1]['product_option_value_id'];
} 

Answer 2

使用foreach代替，

foreach ( $array['product'] as $product)
    { 
       echo $product['id'];
       echo $product['images'][0];
       echo $product['options'][0]['product_option_id'];
       echo $product['options'][0]['option_value'][0]['product_option_value_id'];
       echo $product['options'][0]['option_value'][1]['product_option_value_id'];
    } 

在這里，您將在$array['product']每個元素內循環，並且對於每個循環， $product將具有$array['product']的當前元素。

你嘗試的錯誤在於[$ i]。 對於每個循環$ i將有0,1,2等，數組索引將是$array['product'][0]等，但是沒有那種元素。 如果您的數組是Indexed array ，則此方法有效，但此處它是Associative Array 。

Answer 3

您可能需要這樣的遞歸函數來打印多維數組：

function printIt($data){
    if (is_array($data)){
        foreach ($data as $index=>$slice){
            if (is_array($slice)){
                printIt($slice);
            }else{
                echo $index.": ".$slice."<br>";
            }
        }
    }else{
        echo $data."<br>";
    }
}

printIt($yourArray);

Answer 4

試試這個，

    <?php

foreach($result as $res){
    echo '<pre>'; echo $res['id'];

    if(is_array($res['options']) &&  !empty($res['options'])) {
        foreach($res['options'] as $option) {
            echo '<pre>'; echo ($option['product_option_id']);


            if(is_array($option['option_value']) &&  !empty($option['option_value'])) {
                foreach($option['option_value'] as $option_value) {
                    echo '<pre>'; echo $option_value['product_option_value_id'];
            }


        }
    }
}
?>
