访问双层数组时发生php错误

我的数据位于返回值的第二层，我试图访问单个元素。数组（[success]=>1[return]=>Array（[0]=>Array 我尝试了['return'，因为这是关键，这是我需要的，但得到了相同的错误或明显更糟

错误：

Array to string conversion in orders.php on line 10

代码：

---

…

问题在于，对于上面代码中的

echo$x

语句，

$x

是一个数组，而不是字符串

echo

函数需要一个字符串，因此出现的错误是因为PHP自动尝试将传递给

echo

的参数转换为字符串，但由于传递数组而失败

试试这个：

if (isset($result['return'])) {
    foreach($result['return'] as $result_item) {
        echo(var_export($result_item, true));
    }
} else {
    echo 'No results';
}

---

我真的不明白你想在这里做什么，但是如果你想打印数组的内容，你应该使用

print\r

你可以只使用函数print\r（），我必须将值复制到哈希表，就是这样！我离数组很近，到处都是。但这就是我要找的。
