PHP通过嵌套的JSON循环查找值

我正在尝试循环遍历嵌套的JSON数据，以找到具有特定字符串的名称，并提取与该名称相关联的字符串值。在本例中，名称字符串为“myKey”，值字符串为“12345678”

在看了几个类似的问题和文档之后，我尝试了不同的方法，例如使用对象或关联数组，但最终还是无法获得所需的信息或收到错误

错误类型：

Notice: Array to string conversion

Warning: Invalid argument supplied for foreach()

Trying to get property of non-object

下面是使用$myObj=JSON_decode（$result）解码的JSON片段

以下是我尝试过的PHP代码片段：

$myObj = json_decode($result);
// or I have tried
// $myObj = json_decode($result, true);


// here are different snippets of code I tried
foreach($myObj->result as $test) {
    echo '<pre>';
    print_r($test->name);
    echo "<br>";
    if ($test->name == "Units") {
        $resultName = $test->name;
        echo $resultName . "<br>";
    }
    echo '</pre>';
}

/*
foreach($myObj->result as $test) {
    echo $test . "<br>";
    foreach($test->name as $test1) {
        echo $test1 . "<br>";
        foreach($test1->value as $test2) {
            echo $test2 . "<br>";
        }
    }
}
*/

/*
foreach($myObj->result as $test) {
    if (($test->name) == "Units") {
        // grab the value that corresponds to the name
        $units = $test->name;
        if (($units->name) == "Components") {
            $components = $units->name;
            print_r($components);
        }
    }
}
*/

但是值的位置可能不同，所以我需要通过循环找到对象的名称

有谁能提供更好的使用对象（甚至可能是关联数组）的方法吗

更新为包含原始JSON片段（解码前）

---

感觉需要一些递归函数（在找到结果之前调用自身的函数）来查找嵌套数组中的值

看看

当然，您必须更改该问题中的函数，但我曾经遇到过类似的问题，而且非常有用。

下面是编码和解码的代码。希望这对你有帮助

您是否考虑过将此结果转换为一个新的（关联）数组，以便管理关键点/位置并轻松循环数组？嗯，我只看到$result是一个数组（3），而不是一个对象。@Adder结果是一个对象数组；）你能发布一个你必须转换的原始json的示例吗？@Eineki我已经更新了帖子，在json_decode函数之前显示了原始json的片段

$myObj = json_decode($result);
// or I have tried
// $myObj = json_decode($result, true);


// here are different snippets of code I tried
foreach($myObj->result as $test) {
    echo '<pre>';
    print_r($test->name);
    echo "<br>";
    if ($test->name == "Units") {
        $resultName = $test->name;
        echo $resultName . "<br>";
    }
    echo '</pre>';
}

/*
foreach($myObj->result as $test) {
    echo $test . "<br>";
    foreach($test->name as $test1) {
        echo $test1 . "<br>";
        foreach($test1->value as $test2) {
            echo $test2 . "<br>";
        }
    }
}
*/

/*
foreach($myObj->result as $test) {
    if (($test->name) == "Units") {
        // grab the value that corresponds to the name
        $units = $test->name;
        if (($units->name) == "Components") {
            $components = $units->name;
            print_r($components);
        }
    }
}
*/

print_r($myObj->result[1]->value[0][5]->value[0][1]->name);
print_r($myObj->result[1]->value[0][5]->value[0][1]->value);
