function getGoogleAddressCoordinates()
{
//using the google maps api to get the long and lat coordinates of addresss
//using form post variables
$address =trim($_POST['address']);
$city = trim($_POST['city']);
$state = trim($_POST['state']);
//formats the address add '+' into space
$address = str_replace( ' ', '+' ,$address);
$city = str_replace( ' ', '+', $city);
$address = preg_replace("[^A-Za-z0-9]", '+', $address ); //remove non alpha numeric chars such as extra spaces.
$address_str = $address.',+'. $city.',+'.$state;
$geo_url = "http://maps.google.com/maps/api/geocode/json?address=$address_str&sensor=false";
//echo $geo_url;
//echo file_get_contents($geo_url);
$json_result = json_decode(file_get_contents($geo_url));
$geo_result = $json_result->results[0];
$coordinates = $geo_result->geometry->location;
//see if the it is locating the real address or just apox location, or in most cases a bad address
if($geo_result->types[0] == 'street_address')
$coordinates->valid_address = TRUE;
else
$coordinates->valid_address = FALSE;
return $coordinates;
}

You can use the json_encode and json_decode functions to parse json data.

I would like to parse specific data from google geocode as I mentioned above. do you know the structure of parsing these data? Thanks.
Using the PHP PECL json library
json_decode()
http://php.net/manual/en/function.json-encode.php
Just an advice, if the function doesn't return anything that means that there is a syntax error into the JSON, it will not raise any error or log.
