这是关于我的另一个问题：Saving Latitude and Longitude values to a MySQL Database iOS
你能告诉我这段代码是否将我的纬度和经度值保存为字符串或数字。如果它保存为字符串，你能告诉我如何将它们保存为数字吗？
我还为它们设置了 mysql 字段作为浮点类型。
PHP
<?php
$username = "username";
$database = "database";
$password = "password";
mysql_connect(localhost, $username, $password);
@mysql_select_db($database) or die("unable to find database");
$name = $_GET["name"];
$address = $_GET["address"];
$city = $_GET["city"];
$county = $_GET["county"];
$country = $_GET["country"];
$postcode = $_GET["postcode"];
$date = $_GET["date"];
$time = $_GET["time"];
$latitude = $_GET["latitude"];
$longitude = $_GET["longitude"];
$query = "INSERT INTO map VALUES ('', '$name', '$address', '$city', '$county', '$country', '$postcode', '$date', '$time', '$latitude', '$longitude')";
mysql_query($query) or die(mysql_error("error"));
mysql_close();
?>
