请原谅我这个问题的简单性,但我是使用API和JSON的新手。但我有一个JSON文件,我想打印出"文本"值"持续时间"。我怎么能这样做?
{
"destination_addresses" : [ "San Francisco, CA, USA" ],
"origin_addresses" : [ "Seattle, WA, USA" ],
"rows" : [
{
"elements" : [
{
"distance" : {
"text" : "808 mi",
"value" : 1299998
},
"duration" : {
"text" : "12 hours 27 mins",
"value" : 44846
},
"status" : "OK"
}
]
}
],
"status" : "OK"
}
我正在尝试使用:
$url = 'https://maps.googleapis.com/maps/......'
$content = file_get_contents($url);
$json = json_decode($content, true);
echo $json['rows']['elements']['duration']['text'];
非常感谢!

你应该这样做:
print(pd.read_csv('data.csv', lineterminator='\n'))
country metric 2011 2012
0 USA GDP\r 7 4
1 USA Pop.\r 2 3
2 GB GDP\r 8 7
输出:
12小时27分钟
请注意,在echo $json['rows'][0]['elements'][0]['duration']['text'];
中,您标记了新数组json
,因此您忘记使用[
。
<小时/> 这是结构(来自
[SOME_NUMBER]
):
print_r($json);
您也可以将其用作对象。它会是这样的:
Array
(
[destination_addresses] => Array
(
[0] => San Francisco, CA, USA
)
[origin_addresses] => Array
(
[0] => Seattle, WA, USA
)
[rows] => Array
(
[0] => Array
(
[elements] => Array
(
[0] => Array
(
[distance] => Array
(
[text] => 808 mi
[value] => 1299998
)
[duration] => Array
(
[text] => 12 hours 27 mins
[value] => 44846
)
[status] => OK
)
)
)
)
[status] => OK
)
输出:
12小时27分钟
