Question

server.php

// some code here ..... 
// this is the end of the file:

$json_data = array(
    'test1'=>hello world,
    'test2'=>hello stack
);

echo json_encode($json_data);

api.php

$text = api("http://example.com/?TEXT=$text&APIKEY=$apikey");
// return the json from server.php file
echo $text;

function api($url) {
     $ch = curl_init();
     $timeout = 20;
     curl_setopt($ch, CURLOPT_URL, $url);
     curl_setopt($ch, CURLOPT_POST, TRUE);
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
     curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
     curl_setopt($ch, CURLOPT_TIMEOUT, 20);
     $data = curl_exec($ch);
     curl_close($ch);
     return $data;
}

文件api.php成功返回json

{"test1":"hello world","test2":"hello stack"}

问题是当我尝试解析返回的JSON以获得test1的值时，它没有显示任何内容。

我尝试了类似的东西，但无法解析JSON。

$obj=json_decode($text);
// dosent show anything
echo $obj->test1;

Answer 1

在数组中的值周围加上引号。

   $json_data = array(

    'test1'=>"hello world",
    'test2'=>"hello stack");

从curl解析json数据
