Geocode API query limit exceed
<p>Geocode API allowed 2500 requests per day, but my site is not sending such requests in a single day. is my code sending automated requests?</p>

<pre><code>function getmap($addrss,$location,$city){

$address = $addrss.' '.$city.' '.$location;
$prepAddr = urlencode($address);

$geocode=file_get_contents('http://maps.google.com/maps/api/geocode/json?address='.$prepAddr.'&amp;sensor=false');

$output= json_decode($geocode);

$lat = $output-&gt;results[0]-&gt;geometry-&gt;location-&gt;lat;
$long = $output-&gt;results[0]-&gt;geometry-&gt;location-&gt;lng;
$retval = $lat.'*'.$long;
return $retval;
</code></pre>

<p>}</p>
