How to obtain the IP address and region in php through Chianz.com, chianz.comip

The example in this article describes how php obtains the IP address and region through Chianz.com. Share it with everyone for your reference. The specific analysis is as follows:

The result obtained by an IP is not very perfect. The reason is that the IP resolution of ip138 is not very detailed when dealing with foreign addresses, so I re-wrote a code using Chianz.com. The example code is as follows:

$ipAddr = "4.4.44.4";
$ipChinazAddr = "http://tool.chinaz.com/IP/?IP=".$ipAddr;
$contents = file_get_contents($ipChinazAddr);
$pattern = "/==>>.+
/";
$string = $contents;
preg_match_all($pattern,$string,$addrArray);
$num = count($addrArray[0]);
$pattern = "/(==>>).+(==>>s)/";
for($i = 0;$i<$num;$i++){
$addrArray[0][$i] = preg_replace($pattern,"",$addrArray[0][$i]);
}
echo "

"; <br>
print_r($addrArray); <br>
echo "

";
?>

I hope this article will be helpful to everyone’s PHP programming design.
