一些常用的封装函数（获取当前ip、查找手机号归属地、根据ip获取所在地区）

1. 获取请求ip

// 获取请求ipfunction ip() {if(getenv(&＃39;HTTP_CLIENT_IP&＃39;) && strcasecmp(getenv(&＃39;HTTP_CLIENT_IP&＃39;), &＃39;unknown&＃39;)) {$ip &＃61; getenv(&＃39;HTTP_CLIENT_IP&＃39;);} elseif(getenv(&＃39;HTTP_X_FORWARDED_FOR&＃39;) && strcasecmp(getenv(&＃39;HTTP_X_FORWARDED_FOR&＃39;), &＃39;unknown&＃39;)) {$ip &＃61; getenv(&＃39;HTTP_X_FORWARDED_FOR&＃39;);} elseif(getenv(&＃39;REMOTE_ADDR&＃39;) && strcasecmp(getenv(&＃39;REMOTE_ADDR&＃39;), &＃39;unknown&＃39;)) {$ip &＃61; getenv(&＃39;REMOTE_ADDR&＃39;);} elseif(isset($_SERVER[&＃39;REMOTE_ADDR&＃39;]) && $_SERVER[&＃39;REMOTE_ADDR&＃39;] && strcasecmp($_SERVER[&＃39;REMOTE_ADDR&＃39;], &＃39;unknown&＃39;)) {$ip &＃61; $_SERVER[&＃39;REMOTE_ADDR&＃39;];} else {$ip &＃61; &＃39;unknown&＃39;;}return preg_match ( &＃39;/[\d\.]{7,15}/&＃39;, $ip, $matches ) ? $matches [0] : &＃39;&＃39;;}

2.获取手机号归属地

/ 获取手机号归属地
function GetPhoneCity($phone) {
$url &＃61; &＃39;https://cx.shouji.360.cn/phonearea.php?number&＃61;&＃39;.$phone; //360
$ch &＃61; curl_init();
$timeout &＃61; 10;
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents &＃61; curl_exec($ch);
curl_close($ch);
$info&＃61;json_decode($file_contents,true);
return $info;
}

3.获取请求ip的地区

// 获取请求ip的地区function getCityCurl($ip) {$url&＃61;"http://ip.taobao.com/service/getIpInfo.php?ip&＃61;".$ip; $ch &＃61; curl_init(); $timeout &＃61; 5; curl_setopt ($ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents &＃61; curl_exec($ch); curl_close($ch); $ipinfo&＃61;json_decode($file_contents); if($ipinfo->code&＃61;&＃61;&＃39;1&＃39;){ return &＃39;&＃39;;} $city &＃61; $ipinfo->data->region.&＃39; &＃39;.$ipinfo->data->city; return $city; }
