我从下面的函数中获取json：

function webhook_listener($request_data){
    $client = new ZohoCRMClient('Contacts', 'API KEY HERE');

    $parameters = $request_data->get_params();

    if( !isset( $parameters['contactId'] ) || empty($parameters['contactId']) ){
        file_put_contents(plugin_dir_path( __FILE__ ).'invalid.txt', 'No parameter found');
        return array( 'error' => 'no_parameter_given' );
    }else{
        $companyid = $parameters['contactId'];

        file_put_contents(plugin_dir_path( __FILE__ ).'crm.txt', $parameters);

        $record = $client->getRecordById()->id($companyid)->request();

        wp_mail( 'test@gmail.com', 'Post Data', $record );

        $payload = json_decode($record, true);

        $payload = $payload[1]['data']['Company'];

        file_put_contents(plugin_dir_path( __FILE__ ).'record.txt', $payload);

       return $payload;
    }
}

您可以尝试这样做：

<?php

$json = '{
    "1": {
        "index": 1,
        "data": {
            "CONTACTID": "3345923000000546002",

    }
}';
$payload = json_decode($json, true);
$error = json_last_error();
if ($error !== JSON_ERROR_NONE) {
    throw new RuntimeException("JSON decode error: $error");
}
var_dump($payload[1]['data']['Company']);

如果不需要关联数组而需要类，请尝试以下操作：

$payload = json_decode($json);
$error = json_last_error();
if ($error !== JSON_ERROR_NONE) {
    throw new RuntimeException("JSON decode error: $error");
}
var_dump($payload->{"1"}->data->Company);

结果是一样的

你必须像这样解码记录

$array=json_decode（$record，true）

然后您可以像这样访问数据

echo$array['1']['data']['Company']

在这里结账

祝你有愉快的一天

在data.json文件中包含json资源

$json = file_get_contents('/tmp/data.json');

或者一串

$json = '{
    "1": {
        "index": 1,
        "data": {
            "CONTACTID": "3345923000000546002",

        }
    }
}';

试试下面的方法

$record = (array) json_decode($json);

print_r($record[1]->data->Company);

输出

3ELLC

这对我很有用：

<?php
$var = json_decode('{
    "1": {
        "index": 1,
        "data": {
            "CONTACTID": "3345923000000546002",

不幸的是，要获取属性名为数字的对象属性非常困难。最好将其解码为数组而不是对象<代码>$record=json_decode（$str，true）

@aynber当我使用json_decode时，我也会收到一个空值，所以我在postman中运行了你的答案，返回的值为空。我还应该提到，我正在函数中使用代码。请尝试一下，如果它不起作用，我会尽力帮助你。请按照SO标准格式化你的问题。你应该先打印$record，然后再尝试解码，并检查是否有任何数据。@urreeK在我的函数中，我返回$record，并在我的帖子中收到json，但是试图从json中获取值时，它总是空的。如果您使用var_dump（$record），您会得到什么？工作得很好

<?php
$var = json_decode('{
    "1": {
        "index": 1,
        "data": {
