[英]How to parse JSON format DATA from Facebook Graph Api with php?
I wrote this php code to fetch data from an url with json format and It seemed like it worked but I dont get anything in the database我写了这个 php 代码来从一个 json 格式的 url 中获取数据,它似乎有效,但我在数据库中没有得到任何东西
<?php
session_start();
$con= mysqli_connect("localhost","root","") or die ("could not connect to mysql");
mysqli_select_db($con,"facebook_data") or die ("no database");
$url = "https://graph.facebook.com/209024949216061/feed?fields=created_time,from,type,message&access_token=XXXXXXXX";
$ch = curl_init($url);
curl_setopt($ch,CURLOPT_HEADER, false);
$curlResponse = curl_exec($ch);
$data = json_decode($curlResponse,TRUE);
if (is_array($data) || is_object($data)) {
foreach($data as $row){
$id=$row["id"];
$created_time=$row["created_time"];
$type=$row["type"];
$message=$row["message"];
$user_id=$row["from"]["id"];
$username=$row["from"]["name"];
$sql="INSERT INTO group_feed(id, username, created_time, user_id, type, message) VALUES('$id','$username','$created_time','$user_id', '$type', '$message')";
if(!mysql_query($sql,$con))
{
die('Error : ');
}
}
}
?>
I put the $url with the appropriate access_token when I open the link in my browser it displays me the JSON format DATA where the problem could be?当我在浏览器中打开链接时,我将 $url 与适当的 access_token 放在一起,它会向我显示 JSON 格式的数据,问题可能出在哪里?
$url = "http://graph.facebook.com/".$group_id."/feed/?access_token=".$token; $ch = curl_init($url); curl_setopt(CURLOPT_HEADER, false); $curlResponse = curl_exec($ch);

Then you have to parse you curl response using $data = json_decode($curlResponse)
.然后你必须使用$data = json_decode($curlResponse)
解析你的 curl 响应。 You will get an associative array which can be iterated ( foreach
, for
, while
).您将获得一个可以迭代的关联数组( foreach
、 for
、 while
)。 Only you know how to write your SQL queries.只有您知道如何编写 SQL 查询。
Note: If this doesn't work, take a look at the curl_setopt()
function.注意:如果这不起作用,请查看curl_setopt()
