如何從php中的json字符串獲取值？

Question

我已經試過了這段代碼： $ record = $ record ['data']-> Company; 但始終返回為null。 我也試過$ record = $ record [1]-> data-> Company; 這也將導致空值。 我已經閱讀了很多答案並嘗試了解決方案，但對我來說卻無濟於事。

比我更多的經驗，請看看，讓我知道我要去哪里了。

提前致謝

我從下面的函數中獲取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;
    }
}

Answer 1

這個對我有用：

<?php
$var = json_decode('{
    "1": {
        "index": 1,
        "data": {
            "CONTACTID": "3345923000000546002",
            "SMOWNERID": "3345923000000158021",
            "Contact Owner": "Frank Rosa",
            "First Name": "Administrator",
            "Last Name": "Ian",
            "Email": "poojarajan3ellc@gmail.com",

        }
    }
}');

foreach($var as $item) {
    echo $item->data->Company . '<br>';
}
?>

問題出在鍵“ 1”中，您不能像$var->1那樣訪問它，但是可以在數組中對其進行迭代。

Answer 2

您可以嘗試執行以下操作：

<?php

$json = '{
    "1": {
        "index": 1,
        "data": {
            "CONTACTID": "3345923000000546002",
            "SMOWNERID": "3345923000000158021",
            "Contact Owner": "Frank Rosa",
            "First Name": "Administrator",
            "Last Name": "Ian",
            "Email": "poojarajan3ellc@gmail.com",
            "Created Time": "2018-09-19 14:32:35",
            "Modified Time": "2018-09-20 02:48:51",
            "Full Name": "Administrator Ian",
            "Description": "Equity and Empowerment through Education.

            "Last Activity Time": "2018-09-20 02:48:51",
            "Instagram Url": "http://www.instagram.com/3e_llc",

            "Website": "https://www.3ellc.org",
            "Phone_1": "(727) 420-1050",
            "Full Address": "2152 Arcadia Rd, Holiday, FL 34690, USA",
            "Facebook Url": "http://www.facebook.com/3eLLC/",

            "Select Service": "Technology",
            "User ID": "347"
        }
    }
}';
$payload = json_decode($json, true);
$error = json_last_error();
if ($error !== JSON_ERROR_NONE) {
    throw new RuntimeException("JSON decode error: $error");
}
var_dump($payload[1]['data']['Company']);

結果，您將看到：

string(5) "3ELLC"

如果您不需要關聯數組而是類，請嘗試以下操作：

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

結果將是相同的。

Answer 3

1. 您必須像這樣解碼記錄。

   $ array = json_decode（$ record，true）;

2. 然后，您可以像這樣訪問數據。

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

Answer 4

在data.json文件中具有json資源

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

或成串

$json = '{
    "1": {
        "index": 1,
        "data": {
            "CONTACTID": "3345923000000546002",
            "SMOWNERID": "3345923000000158021",
            "Contact Owner": "Frank Rosa",
            "First Name": "Administrator",
            "Last Name": "Ian",
            "Email": "poojarajan3ellc@gmail.com",
            "Created Time": "2018-09-19 14:32:35",
            "Modified Time": "2018-09-20 02:48:51",
            "Full Name": "Administrator Ian",

            "User ID": "347"
        }
    }
}';

嘗試以下

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

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

產量
