而我的Php代码正在将这些数据解码为数组，然后我无法将对象和数组分开。我知道我有多少结果，我可以简单地循环，但我需要知道如何获得这些数据。
<?php
$json = file_get_contents('https://newsapi.org/v2/top-headlines?country=us&apiKey=5d0d49e595dc4b64a2fd3916b617ad8c');
print_r( json_decode($json, true));
$jsons= ( json_decode($json, true));
echo $jsons[0]["article"];
?>
答案 0 :(得分：1)
您的PHP代码错误，@Echo Off
For /F "Delims==" %%A In ('Set DeviceName[ 2^>Nul') Do Set "%%A="
Set "i=0"
For /F "EOL= Delims=" %%A In ('Reg Query "HKLM\SYSTEM\CurrentControlSet\Enum"^
/S /F "{4d36e967-e325-11ce-bfc1-08002be10318}" /D^|Find /I "Enum"'
) Do Set /A i+=1 & For /F "Skip=1 Tokens=2*" %%B In ('Reg Query "%%A"^
/V "FriendlyName" 2^>Nul') Do Call Set DeviceName[%%i%%]=%%C
Set DeviceName[ 2>Nul
Pause
。 - 这不行。
您需要将其替换为echo $jsons[0]["article"];。因此，我认为您对JSON DATA的意思是如何推出或通过数据。
因为您已将assoc参数设置为true，json_decode()将返回一个数组。
首先对代码进行更正，以帮助您了解json和array()的工作原理。
print_r( $jsons["articles"][0] );在这个例子中，我们将推出所有文章。
$json = file_get_contents('https://newsapi.org/v2/top-headlines?country=us&apiKey=5d0d49e595dc4b64a2fd3916b617ad8c');
print_r( json_decode($json, true));
$jsons= ( json_decode($json, true));
print_r( $jsons["articles"][0] );
echo $jsons["articles"][0]['title'];
您可能还想在w3schools.com上看到array()。
答案 1 :(得分：-1)
$jsons不是数组，而是对象。你想要的是$jsons->articles[0]。
