Curl not working, error: couldn't connect to host

I am using curl to get weather information from a specific site api.wunderground.com and the issue is its not working. I have tried using the file_get_contents function also, but its not working either. Here is my code for curl:

function get_web_page($url)
        {
            //echo "curl:url<pre>".$url."</pre><BR>";
        $options = array(
            CURLOPT_RETURNTRANSFER => true,     // return web page
            CURLOPT_HEADER         => false,    // don't return headers
            CURLOPT_FOLLOWLOCATION => true,     // follow redirects
            CURLOPT_ENCODING       => "",       // handle all encodings
            CURLOPT_USERAGENT      => "spider", // who am i
            CURLOPT_AUTOREFERER    => true,     // set referer on redirect
            CURLOPT_CONNECTTIMEOUT => 15,      // timeout on connect
            CURLOPT_TIMEOUT        => 15,      // timeout on response
            CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
            CURLOPT_PROXY          => null,

        );                  

        $ch         = curl_init($url);
        curl_setopt_array( $ch, $options );
        $content    = curl_exec( $ch );
        $err        = curl_errno( $ch );
        $errmsg     = curl_error( $ch );
        $header     = curl_getinfo( $ch,CURLINFO_EFFECTIVE_URL );
        curl_close( $ch );

        $header['errno']   = $err;
        $header['errmsg']  = $errmsg;

        //change errmsg here to errno
        if ($errmsg)
        {
            echo "CURL:".$errmsg."<BR>";
        }
        return $content;
        }

        $url        =   "http://api.wunderground.com/api/67927f145c532a19/geolookup/conditions/q/uae/dubai.json";

        get_web_page($url);

I have checked my server settings, curl is enabled and the server is using port 80. Can anybody help me with this I am out of ideas.

Simply add 

        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_SSL_VERIFYHOST => false,
        CURLOPT_SSL_VERIFYPEER => false,
        CURLOPT_PROXY => false,

it resolved the issue

you just need to echo the output.

echo get_web_page($url);

EDIT:

You may also use file_get_contents

<?php
$url="http://api.wunderground.com/api/67927f145c532a19/geolookup/conditions/q/uae/dubai.json";
echo file_get_contents($url);
?>

Code update: 

<?php
function get_web_page($url)
{    
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 120);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $curl_result = curl_exec($ch);
    curl_close ($ch);
    return $curl_result;
}

$url="http://api.wunderground.com/api/67927f145c532a19/geolookup/conditions/q/uae/dubai.json";
echo get_web_page($url);
?>

The API seems to block suspicious User Agents. Try using a standard browser User Agent instead of spider.

With normal ( a browser's user agent ) , the API returns normal response .

i tried the same code and got response as

{ "response": { "version": "0.1" ,"termsofService": "http://www.wunderground.com/weather/api/d/terms.html" ,"features": { "geolookup": 1 , "conditions": 1 }

The above code is right. you simple forget to print the value returned by function
