从给定数组中获取值

Question

我有一个像这样存储在$ result中的数组

$result=$array

通过使用echo $ result我得到以下数组

Array
(
    [success] => 1
    [product] => Array
        (
            [id] => 83
            [seo_h1] =>

我可以像这样单独获取结果

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

但希望使用for循环获取每个数据，甚至是最内部的数据。 为此我试过这个

$c=count($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'];
    } 

但它没有显示任何结果，任何人都可以告诉它是如何做到的

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'];
    } 

在这里，您将在$array['product']每个元素内循环，并且对于每个循环， $product将具有$array['product']的当前元素。

你尝试的错误在于[$ i]。 对于每个循环$ i将有0,1,2等，数组索引将是$array['product'][0]等，但是没有那种元素。 如果您的数组是Indexed array ，则此方法有效，但此处它是Associative Array 。

Answer 3

您可能需要这样的递归函数来打印多维数组：

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

试试这个，

    <?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'];
            }


        }
    }
}
?>
