Google maps failed to open stream Error - php

Question

I'm uploading a csv file and getting address field in $address variable, but when I pass $address to google maps, its showing me error,
file_get_contents(http://maps.googleapis.com/maps/api/geocode/json?address=9340+Middle+River+Street%A0%2COxford%2CMS%2C38655): failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request.
I searched for its solution, I found one that to encode only address but its also not working for me...
CODE
if (!empty($address)) {
$geo = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=' . urlencode($address));
$geo = json_decode($geo, true);
if ($geo['status'] = 'OK') {
if (!empty($geo['results'][0])) {
$latitude = $geo['results'][0]['geometry']['location']['lat'];
$longitude = $geo['results'][0]['geometry']['location']['lng'];
}
$mapdata['latitude'] = $latitude;
$mapdata['longitude'] = $longitude;
return $mapdata;
} else {
$mapdata['latitude'] = "";
$mapdata['longitude'] = "";
return $mapdata;
}
}
Error is at line
$geo = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=' . urlencode($address));
Have I missed anything.!
Any help is much appreciated.. Thanks

Answer 1

you need to use google api key
function getLatLong($address){
if(!empty($address)){
//Formatted address
$formattedAddr = str_replace(' ','+',$address);
//Send request and receive json data by address
$geocodeFromAddr = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address='.$formattedAddr.'&sensor=false');
$output = json_decode($geocodeFromAddr);
//Get latitude and longitute from json data
$data['latitude'] = $output->results[0]->geometry->location->lat;
$data['longitude'] = $output->results[0]->geometry->location->lng;
//Return latitude and longitude of the given address
if(!empty($data)){
return $data;
}else{
return false;
}
}else{
return false;
}
}
Use getLatLong() function like the following.
$address = 'White House, Pennsylvania Avenue Northwest, Washington, DC, United States';
$latLong = getLatLong($address);
$latitude = $latLong['latitude']?$latLong['latitude']:'Not found';
$longitude = $latLong['longitude']?$latLong['longitude']:'Not found';
To specify a Google API key in your request, include it as the value of a key parameter.
$geocodeFromAddr = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address='.$formattedAddr.'&sensor=true_or_false&key=GoogleAPIKey');
i hope this will help you.

It looks like the problem is with your data set. The part of the url that is being encoded as %A0 by urlencode($address) is a special non-breaking space character, rather than a regular space.
See here for more information on the difference:
Difference between "+" and "%A0" - urlencoding?
The %A0 character isn't accepted in this context, but you can do a quick str_replace() on the result of urlencode() to replace all these special space characters with the + symbols that regular spaces would have resulted in.
$geo = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=' . str_replace('%A0', '+', urlencode($address)));
