                         [image] =>

) ) ) [Networking] => Array

该数组是 $products

<?php foreach ($products as $product): ?> 
   <div class="box-active">
    <div class="line">
    <div class="text left">
    <p><?php print key($product); ?></p>

它为所有三个打印 0

试试这个：

<?php foreach ($products as $key => $product): ?> 
   <div class="box-active">
    <div class="line">
    <div class="text left">
    <p><?php print $key; ?></p>
