PHP [function.file-get-contents]: Failed to open stream - php

Question

This is really annoying me, the php script was working and returning the weather from open weather map but literally all of a sudden the php script takes forever to execute and the following error is produced:
Warning: file_get_contents(http://api.openweathermap.org/data/2.5/weather?lat=&lon=&units=metric&cnt=7&lang=en&key=f38a36af9e4965dd5192ba4282abe070) [function.file-get-contents]: failed to open stream: Connection timed out in /xxx/xxx/public_html/fullweather.php on line 15
Any help would be appreciated. The php script can be viewed below. Only the beginning is important (first 18 lines) but I have included the full thing.
<?php
$lat = $_POST["latitude"];
$lon = $_POST["longitude"];
$url="http://api.openweathermap.org/data/2.5/weather?lat=".$lat."&lon=".$lon."&units=metric&cnt=7&lang=en&key=f38a36af9e4965dd5192ba4282abe070";
// Make call with cURL
$session = curl_init($url);
curl_setopt($session, CURLOPT_RETURNTRANSFER,true);
$json = curl_exec($session);
$json=file_get_contents($url);
$data=json_decode($json,true);
class weatherdata
{
public $temp = "";
public $weather = "";

public $area = "";
public $humidity = "";
public $humidpressure = "";
public $weatherdesc = "";

}
$data1 = $data['main']['temp'];

$data9 = $data['main']['temp_max'];
$data10 = $data['wind']['speed'];
$data12 = $data['wind']['deg'];
$weatherdata = new weatherdata();
$weatherdata->temp = $data1;
$weatherdata->weather = $data2;
$weatherdata->clouds = $data3;
$weatherdata->area = $data4;
$weatherdata->humidity = $data5;
$weatherdata->humidpressure = $data6;
$weatherdata->weatherdesc = $data7;
$weatherdata->tempmin = $data8;
$weatherdata->tempmax = $data9;
$weatherdata->windspeed = $data10;
$weatherdata->winddirec = $data12;
$output[] = $weatherdata;
print(json_encode($output));
?>

Answer 1

I think the API was just down, cause the link is working for me right now.
Try one more time.

Answer 2

May be the API had change it's url by the time. Try to check the documentation for any updated information. I think that they could change it and your code couldnt find because this $url doesn't exist anymore.

Answer 3

i added https instead of http in url and it worked.
so maybe change http in url like this url.
$url="https://api.openweathermap.org/data/2.5/weather?lat=".$lat."&lon=".$lon."&units=metric&cnt=7&lang=en&key=f38a36af9e4965dd5192ba4282abe070";
Edit
Also you should not show your api key to anyone as some one can use it.
