坐标功能有时不起作用

Question

我正在使用这个函数来获取任意地址的坐标：

function getCoordinates($address) {
    $address = str_replace(" ", "+", $address); // replace all the white space with "+" sign to match with google search pattern
    $address = str_replace("-", "+", $address); // replace all the "-"  with "+" sign to match with google search pattern
    $url = "http://maps.google.com/maps/api/geocode/json?address=$address";
    $response = file_get_contents($url);
    $json = json_decode($response,TRUE); //generate array object from the response from the web
    return ($json['results'][0]['geometry']['location']['lat'].",".$json['results'][0]['geometry']['location']['lng']);
}

有时它有效，有时它只为同一地址获得“，”。

我需要使用其他功能吗？

试试这个

$url = "http://maps.google.com/maps/api/geocode/json?address=".$address;
