使用PHP和MySQL数据库批量查找IPv6地址

Posted 2021-02-23

The code below can be used to lookup IP address in bulk in return of geolocation information using php programming languages and mysql database. In this tutorial, we use the IP2Location LITE database to lookup country of origin from the visitor's IP address. Free databases are available for download at IP2Location LITE database.

<?php
 
	//MYSQL configuration
	$mysql_server = "mysql_server.com";
	$mysql_user_name ="User ID";
	$mysql_user_pass ="password";
 
	//Connect to database
	$link = mysql_connect($mysql_server,$mysql_user_name,$mysql_user_pass) or die("could not connect to MySQL Database");
 
	//Check database connection
	if(!$link)
	{
		echo "Database error.";
	}
	else
	{
		mysql_select_db("ip2location") or die("could not select database");
		echo "Database is Connected .";
		echo "<br><br>";
	}
 
	//Display for user input
	echo "";
	echo "<title>IP Query in Bulk</title>";

	echo "";
 
 
	//File submitted
	if(isset($_POST['submit']))
	{
