发现之前有一个脚本没有写完，简单扩充了一下。获取IP使用的是经典的逻辑，地理定位使用的是SINA的通用接口。
使用方法详见源码：
复制代码 代码如下:<?php/* * GET LOCATION BY SINA IP INTERFACE * * @SOULTEARY 2013.04.14 */classIP{ private $args=array(); function__construct() { $this->args=self::init_args(func_get_args()); $ip=self::GetIP(); $ret=preg_match_all("/(d+.){3}d+/i",$ip,$result); if(!$ret){ returnfalse; }else{ $result=$result[0]; } if(isset($this->args["ONLYIP"])&&$this->args["ONLYIP"]==true){ if(isset($this->args["FORMAT"])&&$this->args["FORMAT"]=="JSON"){ $result=json_encode($result); }else{ $result=implode(",",$result); } if(isset($this->args["ECHO"])&&$this->args["ECHO"]==true){ echo$result; returntrue; }else{ return$result; } }else{ $apiURL="http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip=".$result[0]; if(isset($this->args["FORMAT"])&&$this->args["FORMAT"]=="JSON"){ $apiURL.="&format=json"; $return=$this->ipCURL($apiURL); }else{ $return=$this->ipCURL($apiURL); $return=iconv("GBK//IGNORE","UTF-8",$return); } if(isset($this->args["ECHO"])&&$this->args["ECHO"]==true){ echo$return; returntrue; }else{ return$return; } } } public functioninit_args($args) { $result=array(); for($i=0,$n=count($args);$i<$n;$i++){ $result=self::associative_push($args[$i],$result); } return$result; } public functionassociative_push($arr,$tmp) { if(is_array($tmp)){ foreach($tmpas$key=>$value){ $arr[$key]=$value; } return$arr; } returnfalse; } public functionGetIP() { if(isset($_SERVER["HTTP_X_FORWARDED_FOR"])&&$_SERVER["HTTP_X_FORWARDED_FOR"]&&strcasecmp($_SERVER["HTTP_X_FORWARDED_FOR"],"unknown")){ return$_SERVER["HTTP_X_FORWARDED_FOR"]; }elseif(isset($_SERVER["REMOTE_ADDR"])&&$_SERVER["REMOTE_ADDR"]&&strcasecmp($_SERVER["REMOTE_ADDR"],"unknown")){ return$_SERVER["REMOTE_ADDR"]; } } private functionipCURL($url) { $ch=curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_HEADER,0); ob_start(); curl_exec($ch); curl_close($ch); $result=ob_get_contents(); ob_end_clean(); return$result; }} ?><!DOCTYPE html><html><head> <meta charset="utf8"> <title>demo</title> <script type="text/javascript"> varip="<?php new IP(array("ONLYIP"=>true, "ECHO"=>true));?>"; vardata=<?php newIP(array("FORMAT"=>"JSON","ECHO"=>true));?>; varresult=""; for(oo indata){ result+=oo+":"+data[oo]+""; } alert(result+ip); </script></head><body><h1>CODE:</h1> <h2>GETIP</h2> <p>"ONLYIP"=>true,"ECHO"=>true</p> <p><?phpnewIP(array("ONLYIP"=>true,"ECHO"=>true));?></p> <P>"ONLYIP"=>true,"FORMAT"=>"JSON","ECHO"=>true</P> <p><?phpnewIP(array("ONLYIP"=>true,"FORMAT"=>"JSON","ECHO"=>true));?></p> <h2>GET Location</h2> <p>"ECHO"=>true</p> <p><?phpnewIP(array("ECHO"=>true));?></p> <p>"FORMAT"=>"JSON","ECHO"=>true</p> <p><?php newIP(array("FORMAT"=>"JSON","ECHO"=>true));?></p></body></html>
