Google Geocode API - 在PHP中回显特定的详细信息

Question

I'm using this script to get the geo-code information from Google but I don't know how to filter out just specifics such as Lat, Lon, Town, County. Here is my code (which I beleive will work under the new API-3?):

<?php
$address="LS1 7AS";
$result=file_get_contents("http://maps.google.com/maps/api/geocode/json?address=" . urlencode($address) . "&sensor=false" );
    $geocodedinfo=json_decode($result);

print_r($geocodedinfo);
?>

This prints out all of the information I need but as a block, I just want to have some of them so I can insert it into a table, for example:

$town = "town from result";
$county = "county from result";
$lat = "lat from result";
$lon = "lon from result";

Answer 1

First of all You need to modify your API output format.Use output format json because you have already used json_decode function.

$address="LS1 7AS";
"http://maps.google.com/maps/api/geocode/json?address=" . urlencode($address) . "&sensor=false";

And you variables should look like :

$geocodedinfo=json_decode($result);

You have to check return status :

if($geocodedinfo->status == 'OK') {
     $country = $geocodeinfo->results[0]->address_components[3]->long_name;
     $town = $geocodeinfo->results[0]->address_components[2]->long_name;
     $lat = $geocodeinfo->results[0]->geometry->location->lat;
     $lon = $geocodeinfo->results[0]->geometry->location->lng;
}
