php code to convert postal code to longitude and latitude

[sungpeng]

Check is there a php code to convert postal code to longitude and latitude? Thank

I'm sure there is, but your best bet would probably be to use js and flash with mapquest API.. and lat/long will be too much of a guess or estimate than an actual pin point location

<?php
// three parts to the querystring: q is address, output is the format, key is the GAPI
$key = 'your key';
$location = 'singapore'
$url = 'http://maps.google.com/maps/geo?q='.urlencode($location).'&output=xml&key='.$key;

sleep(1);


$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER,0);
curl_setopt($ch, CURLOPT_VERBOSE,0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_FRESH_CONNECT,1);
// I'm telling google maps im using Chrome because this process will be automated in future uses 
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/525.19 (KHTML, like Gecko) Chrome/0.3.154.9 Safari/525.19');

// capture anything in output so script wont break
ob_start();
$xml = curl_exec($ch);
ob_get_clean();

// check for errors
$error = curl_error($ch);

echo $xml;

?>

 

 

Result below

Queensland, Australia 200 geocode

Queensland, Australia

AUAustraliaQLD 145.774,-19.70

 

How to break apart the echo $xml so that one variable is longitude only, one variable is latitude only. Do you have any javascript to recommend also? Thank

u should be able to use simplexml_load_string assuming google gives you XML as a return and then probably do $xml->latitude
