Question

我有这件JSON，我需要FACETS。

我设法得到了＆＃34; nbHits＆＃34;但我正在努力获得＆＃34; facets＆＃34;

$res = "the json below"

$res = json_encode($res);

$obj = json_decode($res);

print $obj->{'nbHits'}; /// 1116

我试过了

print $obj['facets']

和

print $obj['facets'][0]

我遗漏了一些简单的东西，感谢任何帮助。

Answer 1

结果已经是json编码格式，为什么你再次编码呢？

要抓住 facets 上的否值，请尝试$obj->facets->appt->no

$res = 'Your JSON goes here';
//-----Don't do again json_encode() again here
$obj = json_decode($res); 
print '<pre>';
print_r($obj);
print '</pre>';
echo $obj->facets->appt->no;

或通过将其解析为数组

，让生活更轻松

$array = json_decode($res,1); //see second parameter here
print '<pre>';
print_r($array);
print '</pre>';
echo $array['facets']['appt']['no'];
echo $array['facets']['hasOpened']['yes'];
