前面已经分享了PHP常用功能代码片段(1~5)和PHP常用功能代码片段(6~10)，今天是第三篇，也就是第11到15这5个实现代码片段，希望可以帮到jquery学堂群里面的成员和广大对PHP开发的网友们提高开发效率，以下是第三篇文章。

11、PHP实现如何获取网址的PR值

/**功能:对URL进行编码*参数说明:$web_url 网站URL，不包含"http://"*/function HashURL($url){       $SEED = "Mining PageRank is AGAINST GOOGLE’S TERMS OF SERVICE. Yes, I’m talking to you, scammer.";    $Result = 0x01020345;    for ($i=0; $i> 23) & 0x1FF) | $Result ';    $fcontents = file_get_contents("$GoogleURL");    $pagerank = substr($fcontents,9);    if (!$pagerank) return "0";else return $pagerank;}//调用方法echo pagerank("www.jq-school.com");

12、PHP实现为post过来的数据转换编码

$info = array();foreach($_POST as $key => $value){	$info[$key] = iconv("utf-8","gb2312",$value);}

13、PHP实现获取客户端IP地址及所在地区

function address($ip) {    $info = json_decode(file_get_contents('http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip='.$ip.'&format=json'), false);    if ($info ->ret == 1) {        if ($info ->province != $info ->city) {            return $info ->country.",".$info ->province."(".$info ->city.")  ".$info ->district."  ".$info ->desc;        } else {            return $info ->country.",".$info ->province."  ".$info ->district."  ".$info ->desc;        }    } else {        return '地球';    }}
