获取IP有两种方法，复杂的被我注释掉了，如果你想使用复杂的，去掉注释，再把简单的注释掉就可以了。
复制代码代码如下:
<?php
// 复杂获取本地ip地址
/* if (getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$SA_IP = getenv('HTTP_CLIENT_IP');
} elseif (getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$SA_IP = getenv('HTTP_X_FORWARDED_FOR');
} elseif (getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$SA_IP = getenv('REMOTE_ADDR');
} elseif (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$SA_IP = $_SERVER['REMOTE_ADDR'];
} */
$SA_IP=$_SERVER['REMOTE_ADDR'];//简单获取本地ip地址
//定义一个函数根据ip获取城市名，使用新浪的天气预报
function getIPLoc_sina($queryIP){
$url = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=' . $queryIP;
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_ENCODING, 'utf8');
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$location = curl_exec($ch);
$location = json_decode($location);
curl_close($ch);
$loc = "";
if ($location === FALSE)
return "";
if (empty($location->desc)) {
$loc = $location->city;
$full_loc = $location->province . $location->city . $location->district . $location->isp;
} else {
$loc = $location->desc;
}
return $loc;
}
$city = getIPLoc_sina("$SA_IP");</p><p>$citycode = mb_convert_encoding($city, "gb2312", "utf-8");</p><p>$doc = new DOMDocument();
if (<a href="mailto:!@$doc->load("http://php.weather.sina.com.cn/xml.php?city">!@$doc->load("http://php.weather.sina.com.cn/xml.php?city</a>=" . $citycode . "&password=DJOYnieT8234jlsK&day=0")) {
echo "Get data failed!!\n";
return;
}</p><p>$city = $doc->getElementsByTagName("city")->item(0)->nodeValue;
