Oops! My last post on this thread was for a related but different
problem. The following is how I ended up using PHP to read and parse
the json array returned from a Geocode web service request.
<?php
//This code builds a geocode query from an address, issues the query,
reads the json result into a variable which is then parsed into
address components and the Latitude and Longitude of that address.
$postdata = http_build_query(
array(
'var1' => '',
'var2' => ''
)
);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Content-type: application/x-www-form-
urlencoded',
'content' => $postdata
)
);
$context = stream_context_create($opts);
$Street_no = '1600 ';
$Street = ' Pennsylvania Ave ';
$City = 'Washington ';
$State = 'DC';
$Zip = '';
$jsonStreet_no = str_replace(" ", "+", (str_replace(" ", " ",
trim($Street_no)))); //Replace spaces with +
$jsonStreet = str_replace(" ", "+", (str_replace(" ", " ",
trim($Street))));
$jsonCity = str_replace(" ", "+", (str_replace(" ", " ",
trim($City))));
$jsonState = str_replace(" ", "+", (str_replace(" ", " ",
trim($State))));
$jsonZip = str_replace(" ", "+", (str_replace(" ", " ",
trim($Zip))));
$address_string = $jsonStreet_no . '+' . $jsonStreet . ',+' .
$jsonCity . ',+' . $jsonState . ',+' . $jsonZip;
$geocode_string = "http://maps.google.com/maps/api/geocode/json?
address=" . $address_string . "&sensor=false";
print 'geocode_string: ' . $geocode_string;
$result = file_get_contents($geocode_string, false, $context);
?>
<?php
echo "<br>";
?>
<?php
//echo 'Results: ' . $result;
echo "<br>";
?>
<?php
print '<u><b>Here are the parsed results:</B></u>';
echo "<br>";
$json_a = json_decode($result, true); //The 'true' parameter returns
an array. W/O it an object is returned so use -> to deconstruct the
object
print 'Status: ' . $json_a['status'];
echo "<br>";
print 'Results formatted_address: ' . $json_a['results'][0]
['formatted_address'];
echo "<br>";
print 'Results address_StreetNO: ' . $json_a['results'][0]
['address_components'][0]['long_name'];
echo "<br>";
print 'Results address_Street: ' . $json_a['results'][0]
['address_components'][1]['long_name'];
echo "<br>";
print 'Results address_City: ' . $json_a['results'][0]
['address_components'][2]['long_name'];
echo "<br>";
print 'Results address_State: ' . $json_a['results'][0]
['address_components'][5]['short_name'];
echo "<br>";
print 'Results address_Zip: ' . $json_a['results'][0]
['address_components'][7]['long_name'];
echo "<br>";
print 'Results address_County: ' . $json_a['results'][0]
['address_components'][4]['long_name'];
echo "<br>";
print 'Results geometry Latitude: ' . $json_a['results'][0]['geometry']
['location']['lat'];
echo "<br>";
print 'Results geometry Longitude: ' . $json_a['results'][0]
['geometry']['location']['lng'];
echo "<br>";
print 'Results geometry location_type: ' . $json_a['results'][0]
['geometry']['location_type'];
echo "<br>";
$coords = $json_a['results'][0]['geometry']['location']['lat'] . ',' .
$json_a['results'][0]['geometry']['location']['lng'];
print $coords;
echo "<br><br>";
?>
