坐标功能有时不起作用

Question

我使用此功能获取任何地址的坐标：

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']);
}

有时它会起作用，有时它只能得到＆＃34;，＆＃34;对于同一地址。

我需要使用其他功能吗？

试试这个

$ url =＆＃34; http://maps.google.com/maps/api/geocode/json?address=＆＃34;。$ address;
