如何使用php访问Json字段 [英] How to access Json fields by using php

问题描述

我目前正在使用wordpress中的php访问json.我已经成功解码了json，但是当我尝试访问值时却无法获取.我正在尝试访问Cluster_ID和Image，Title值.这是我的api链接

我尝试了以下代码

 <?php/***插件名称:SEC API**/函数myjson8(){$ request = wp_remote_get('http://ec2-13-127-149-66.ap-south-1.compute.amazonaws.com:5000/api/news');if(is_wp_error($ request)){返回false；//提早保释}$ body = wp_remote_retrieve_body($ request);$ data = json_decode($ body);if(！empty($ data)){foreach($ data-> NewsFeed-> data as $ new){回声$ new-> Cluster_ID;foreach($ data-> NewsFeed-> data-> data as $ old){回声$ old->图片;echo $ old-> Title;}}}} 

解决方案

NewsFeed 的类型为数组，因此应为 $ data-> NewsFeed [0]-> data

I am currently working with Accessing json using php in wordpress. I have successfully decoded the json but when i try to access the values it doesn't fetch . I am trying to access the Cluster_ID and Image,Title values. Here's my api link http://ec2-13-127-149-66.ap-south-1.compute.amazonaws.com:5000/api/news

I have tried the following code

<?php

/**

 *Plugin Name: SEC API
 
 **/
function myjson8(){
    $request = wp_remote_get( 'http://ec2-13-127-149-66.ap-south-1.compute.amazonaws.com:5000/api/news' );

if( is_wp_error( $request ) ) {
    return false; // Bail early
}

$body = wp_remote_retrieve_body( $request );

$data = json_decode( $body );

if( ! empty( $data) ) {
    
    foreach($data->NewsFeed->data as $new){
        
        echo $new->Cluster_ID;
        foreach($data->NewsFeed->data->data as $old){
            echo $old->Image;
            echo $old->Title;
        }
    }
    
}
    
}
    

解决方案

The type of NewsFeed is array so It should be $data->NewsFeed[0]->data
