How do you get the longitude and latitude of a specific location using the Google Maps API? This article provides you with a function that takes a certain address as a parameter and returns an array containing longitude and latitude data. Friends in need can refer to it.
The code is as follows: <?php /** * 获取某地址的经纬度 * by http://bbs.it-home.org */ function getLatLong($address){ if (!is_string($address))die("All Addresses must be passed as a string"); $_url = sprintf('http://maps.google.com/maps?output=js&q=%s',rawurlencode($address)); $_result = false; if($_result = file_get_contents($_url)) { if(strpos($_result,'errortips') > 1 || strpos($_result,'Did you mean:') !== false) return false; preg_match('!center:\s*{lat:\s*(-?\d+\.\d+),lng:\s*(-?\d+\.\d+)}!U', $_result, $_match); $_coords['lat'] = $_match[1]; $_coords['long'] = $_match[2]; } return $_coords; } ?> Copy after login |
