php - Google Distance Matrix API error Invalid Request -

i have following code create request in php response google distance matrix api:

//get info google $map_url = 'https://maps.googleapis.com/maps/api/distancematrix/json'; $midnight = strtotime('tomorrow midnight'); $params = array(     'units' => 'metric',     'origins' => str_replace(' ', '+', str_replace('.', '', $arr['address'])),     'destinations' => str_replace(' ', '+', str_replace('.', '', $rink_arr['address'])),     'traffic_model' => 'best_guess',     'departure_time' => $midnight + $rink_arr['avg_time'],     'key' => 'api_key' );  //get data $url = $map_url.'?'.http_build_query($params); $json = file_get_contents($url);     echo '<pre>'; echo $url.'<br><br>'; print_r($json); echo '</pre>'; exit(); 

when run code following response:

https://maps.googleapis.com/maps/api/distancematrix/json?units=metric&origins=2141+southview+ave%2c+innisfil%2c+on+l9s+1h4&destinations=190+bayview+dr%2c+barrie%2c+on+l5n+9b4&traffic_model=best_guess&departure_time=1479523235&key=api_key  {    "destination_addresses" : [],    "origin_addresses" : [],    "rows" : [],    "status" : "invalid_request" } 

but here's catch when copy url above response , paste in browser works. following response:

{    "destination_addresses" : [ "190 bayview dr, barrie, on l4n 2z4, canada" ],    "origin_addresses" : [ "2141 southview ave, innisfil, on l9s 1h4, canada" ],    "rows" : [       {          "elements" : [             {                "distance" : {                   "text" : "9.0 km",                   "value" : 9027                },                "duration" : {                   "text" : "13 mins",                   "value" : 758                },                "duration_in_traffic" : {                    "text" : "12 mins",                    "value" : 720                },                "status" : "ok"             }          ]       }    ],    "status" : "ok" } 

has had similar problem , know why case? have tried changing url doesn't make sense works in browser , not in file_get_contents. have tried curl , got same response. provide.
