Comment extraire plusieurs données de google maps en utilisant php et curl?

Question

Voici un code simple que j'essaie de lancer mais qui ne contient aucune donnée. Quelqu'un pourrait-il aider? Merci!!

<?php 

$addr = "Hotels in ottawa canada"; 
$a = urlencode($addr); 
$geocodeURL = 
"https://maps.googleapis.com/maps/api/geocode/json?address=$a&sensor=false&key=my key"; 

$ch = curl_multi_init($geocodeURL); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
$result = curl_multi_exec($ch); 
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
curl_close($ch); 

$geocode = json_decode($result); 

$lat = $geocode->results[$i]->geometry->location->lat; 
$lng = $geocode->results[$i]->geometry->location->lng; 
echo $formatted_address = $geocode->results[$i]->formatted_address; 
echo $geo_status = $geocode->status; 
echo $location_type = $geocode->results[0]->geometry->location_type; 
echo $location_type = $geocode->results[$i]->geometry->premise; 
echo $street_address = $geocode->results[$i]->street_address;

Si vous cherchez à passer plusieurs adresses en parallèle au api google puis analyser les résultats comme l'un, Ive mis en place un petit exemple qui fait exactement cela et fixé votre code multi boucle. J'espère que cela aide.

<?php 
$urls = array(
'http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true', 
'http://maps.googleapis.com/maps/api/geocode/json?address='.urlencode('Hotels').'&sensor=true'); 

$response = curl_get_multi($urls); 

//Handle response array 
foreach($response as $json){ 
    $result = json_decode($json); 
    //echo $result->status.' '; 

    //Iterate each result 
    foreach($result->results as $res){ 
     //lat 
     echo $res->geometry->location->lat.' '; 
     //lng 
     echo $res->geometry->location->lng.' '; 
     //formatted_address 
     echo $res->formatted_address.' '; 
     //location_type 
     echo $res->geometry->location_type.' '; 
     echo '<br/>'; 
    } 
    echo '<hr />'; 
} 

/** 
* Curl multi function 
* 
* @param Array $urls 
* @return Array 
*/ 
function curl_get_multi($urls) { 
    $curly = array(); 
    $result = array(); 

    $mh = curl_multi_init(); 
    foreach ($urls as $id=>$url) { 
     $curly[$id] = curl_init(); 
     curl_setopt($curly[$id], CURLOPT_URL,   $url); 
     curl_setopt($curly[$id], CURLOPT_HEADER,   0); 
     curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, true); 
     curl_setopt($curly[$id], CURLOPT_TIMEOUT,  2); 
     curl_setopt($curly[$id], CURLOPT_USERAGENT,  'CurlRequest'); 
     curl_setopt($curly[$id], CURLOPT_REFERER,  $url); 
     curl_setopt($curly[$id], CURLOPT_AUTOREFERER, true); 
     curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, true); 

     curl_multi_add_handle($mh, $curly[$id]); 
    } 
    $running = null; 
    do { 
     curl_multi_exec($mh, $running); 
    } while($running > 0); 
    foreach($curly as $id => $c) { 
     $result[$id] = curl_multi_getcontent($c); 
     curl_multi_remove_handle($mh, $c); 
    } 
    curl_multi_close($mh); 
    return $result; 
}
