Convert JSON value to PHP string
提问by
Need to get the value "distance" "text" from the Google Maps API, and convert it into a PHP string.
需要从Google Maps API 中获取值“distance”“text”，并将其转换为PHP 字符串。
For example, https://maps.googleapis.com/maps/api/distancematrix/json?origins=TN222AF&destinations=tn225dj&mode=bicycling&language=gb-FR&sensor=false&units=imperialgives us:
例如，https: //maps.googleapis.com/maps/api/distancematrix/json?origins=TN222AF&destinations=tn225dj&mode=bicycling&language=gb-FR&sensor=false&units=imperial给我们：
{
"destination_addresses" : [ "New Town, Uckfield, East Sussex TN22 5DJ, UK" ],
"origin_addresses" : [ "Maresfield, East Sussex TN22 2AF, UK" ],
"rows" : [
{
"elements" : [
{
"distance" : {
"text" : "3.0 mi",
"value" : 4855
},
"duration" : {
"text" : "22 mins",
"value" : 1311
},
"status" : "OK"
}
]
}
],
"status" : "OK"
}
How would the value "3.0 mi" be changed into a PHP variable from this JSON feed?
如何将值“3.0 mi”从此 JSON 提要更改为 PHP 变量？
Many thanks!
非常感谢！

$json = <<<END_OF_JSON
{
"destination_addresses" : [ "New Town, Uckfield, East Sussex TN22 5DJ, UK" ],
"origin_addresses" : [ "Maresfield, East Sussex TN22 2AF, UK" ],
"rows" : [
{
"elements" : [
{
"distance" : {
"text" : "3.0 mi",
"value" : 4855
},
"duration" : {
"text" : "22 mins",
"value" : 1311
},
"status" : "OK"
}
]
}
],
"status" : "OK"
}
END_OF_JSON;
$arr = (json_decode($json, true));
echo $arr["rows"][0]["elements"][0]["distance"]["text"];
--output:--
3.0 mi

Thanks Dory Zidon, I achieved this in the end and it solved my problem:
感谢 Dory Zidon，我最终实现了这一目标并解决了我的问题：
<?php
$q = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=TN222AF&destinations=tn225dj&mode=bicycling&language=gb-FR&sensor=false&units=imperial";
$json = file_get_contents($q);
$details = json_decode($json);
$distance=$details->rows[0]->elements[0]->distance->text;
echo $distance;
?>
