如何使用curl获取距离？

Question

我有这个网址

http://www.worldatlas.com/travelaids/driving_distance.htm

当我放

From city:
Hollywood, FL, United States
to city:
Washington Avenue, Miami Beach, FL, United States

我距离 18.33mi / 29.51km

我需要一个php脚本，它将上述两个地址发送给url，作为回报，我将获得上述距离。听说使用CURL可以获取帮助/指南，

谢谢

这样的事情应该起作用：

$origin = urlencode("Hollywood, FL");
$destination = urlencode("Washington Avenue, Miami Beach, FL");
$url = "http://maps.googleapis.com/maps/api/directions/json?origin=$origin&destination=$destination&sensor=false";
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, $url);


//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// $output contains the output string
$output = curl_exec($ch);

// close curl resource to free up system resources
curl_close($ch);

$arr = json_decode($output, TRUE);
echo "";
print_r($arr); //get distance from this array
