How does Imperial CMS jump to different pages according to ip? This problem may be often seen in our daily study or work. I hope you can gain a lot from this question. The following is the reference content that the editor brings to you, let's take a look at it!

The code is as follows:

After the client IP address is obtained by the above method, the convertip function is passed into the real address. The code of the convertip ($ip) function is as follows:

The code is as follows:

/ / function: IP address gets the real address function / / Parameter: $ip-IP address / / = = function convertip ($ip) {/ / IP data file path $dat_path = 'QQWry.dat';// check IP address if (! ereg ("^ ([0-9] {1 ip 3}.) {3} [0-9] {1 @ 3} $", $ip)) {return' IP Address Error' } / / Open the IP data file if (! $fd = @ fopen ($dat_path, 'rb')) {return' IP date file not exists or access denied';} / / decompose the IP to get the shaping number $ip = explode ('.', $ip); $ipNum = $ip [0] * 16777216 + $ip [1] * 65536 + $ip [2] * 256 + $ip [3]; / / get the IP data index start and end location $DataBegin = fread ($fd, 4) $DataEnd = fread ($fd, 4); $ipbegin = implode (', unpack ('DataBegin, $DataBegin)); if ($ipbegin)

< 0) $ipbegin += pow(2, 32);$ipend = implode('', unpack('L', $DataEnd));if($ipend < 0) $ipend += pow(2, 32);$ipAllNum = ($ipend - $ipbegin) / 7 + 1;$BeginNum = 0;$EndNum = $ipAllNum;//使用二分查找法从索引记录中搜索匹配的IP记录while($ip1num>

$ipNum | | $ip2num $ipNum) {$EndNum = $Middle;continue;} / / after fetching the previous index, take the next index $DataSeek = fread ($fd, 3); if (strlen ($DataSeek)

< 3) {fclose($fd);return 'System Error';}$DataSeek = implode('', unpack('L', $DataSeek.chr(0)));fseek($fd, $DataSeek);$ipData2 = fread($fd, 4);if(strlen($ipData2) < 4) {fclose($fd);return 'System Error';}$ip2num = implode('', unpack('L', $ipData2));if($ip2num < 0) $ip2num += pow(2, 32);//没找到提示未知if($ip2num < $ipNum) {if($Middle == $BeginNum) {fclose($fd);return 'Unknown';}$BeginNum = $Middle;}}//下面的代码读晕了，没读明白，有兴趣的慢慢读$ipFlag = fread($fd, 1);if($ipFlag == chr(1)) {$ipSeek = fread($fd, 3);if(strlen($ipSeek) < 3) {fclose($fd);return 'System Error';}$ipSeek = implode('', unpack('L', $ipSeek.chr(0)));fseek($fd, $ipSeek);$ipFlag = fread($fd, 1);}if($ipFlag == chr(2)) {$AddrSeek = fread($fd, 3);if(strlen($AddrSeek) < 3) {fclose($fd);return 'System Error';}$ipFlag = fread($fd, 1);if($ipFlag == chr(2)) {$AddrSeek2 = fread($fd, 3);if(strlen($AddrSeek2) < 3) {fclose($fd);return 'System Error';}$AddrSeek2 = implode('', unpack('L', $AddrSeek2.chr(0)));fseek($fd, $AddrSeek2);} else {fseek($fd, -1, SEEK_CUR);}while(($char = fread($fd, 1)) != chr(0))$ipAddr2 .= $char;$AddrSeek = implode('', unpack('L', $AddrSeek.chr(0)));fseek($fd, $AddrSeek);while(($char = fread($fd, 1)) != chr(0))$ipAddr1 .= $char;} else {fseek($fd, -1, SEEK_CUR);while(($char = fread($fd, 1)) != chr(0))$ipAddr1 .= $char;$ipFlag = fread($fd, 1);if($ipFlag == chr(2)) {$AddrSeek2 = fread($fd, 3);if(strlen($AddrSeek2) < 3) {fclose($fd);return 'System Error';}$AddrSeek2 = implode('', unpack('L', $AddrSeek2.chr(0)));fseek($fd, $AddrSeek2);} else {fseek($fd, -1, SEEK_CUR);}while(($char = fread($fd, 1)) != chr(0)){$ipAddr2 .= $char;}}fclose($fd);//最后做相应的替换操作后返回结果if(preg_match('/http/i', $ipAddr2)) {$ipAddr2 = '';}$ipaddr = "$ipAddr1 $ipAddr2";$ipaddr = preg_replace('/CZ88.Net/is', '', $ipaddr);$ipaddr = preg_replace('/^s*/is', '', $ipaddr);$ipaddr = preg_replace('/s*$/is', '', $ipaddr);if(preg_match('/http/i', $ipaddr) || $ipaddr == '') {$ipaddr = 'Unknown';}return $ipaddr;}?>

When using it, use the convertip function to obtain the real address based on the IP address, and then use the following js code to achieve the jump function:

The code is as follows:

Var sf='';// the sf variable here can save the real address obtained by the PHP function if (sf.indexOf ("Hong Kong") > = 0) {_ window.location.href= "http://www.****.com/? Hong Kong";} else if (sf.indexOf ("Guangdong") > = 0) {_ window.location.href= "http://www.****.com/? Guangdong";} Thank you for reading!
