如何使用PHP读取此JSON?
我对JSON格式非常陌生,在我阅读的教程中,我不太了解如何使用php解析。所以我有这个:如何使用PHP读取此JSON?,php,json,Php,Json,我对JSON格式非常陌生,在我阅读的教程中,我不太了解如何使用php解析。所以我有这个: { "type": "FeatureCollection", "features": [ { "type": "Feature", "geometry": { "type": "Point", "coordinates": [
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [
-67.593742,
10.24462
]
},
"properties": {
"id": "669163449",
"accuracyInMeters": 0,
"timeStamp": 1301841780,
"reverseGeocode": "Maracay, Venezuela",
"photoUrl": "https://www.google.com/latitude/apps/badge/api?type=photo&photo=Df7VGy8BAAA.9of56owsf4wI6F4odEQ",
"photoWidth": 96,
"photoHeight": 96,
"placardUrl": "https://g=true&stale=false&lod=4&format=png",
"placardWidth": 56,
"placardHeight": 59
}
}
]
}
我要回显坐标和反向编码。谁能帮我找到正确的方向吗?试试跑步
$decoded = json_decode($json_string, true);
print_r($decoded);
print_r($decoded["features"][0]["geometry"]["coordinates"]);
echo $decoded["features"][0]["properties"]["reverseGeocode"];
其中,$json\u string
是作为字符串的示例json。尝试运行
$decoded = json_decode($json_string, true);
print_r($decoded);
print_r($decoded["features"][0]["geometry"]["coordinates"]);
echo $decoded["features"][0]["properties"]["reverseGeocode"];
其中,$json\u string
是作为字符串的示例json。使用:
您要查找的两个属性是
$obj->features[0]->几何体->坐标
$obj->features[0]->properties->reverseGeocode
$obj->features[0]->几何体->坐标
$obj->features[0]->properties->reverseGeocode
<?php
$json = <<<EOF

现在,您可以根据需要遍历数组
注意:我重新格式化了JSON,因此它实际上是清晰的,使用了。您应该阅读。代码:
