用PHP记录访问外网IP地址，写入一个HTML！

将下面的代码写入一个PHP文件中，可命名为IP.PHP

<?php

$address = $_SERVER["REMOTE_ADDR"];

$referer = $_SERVER["HTTP_REFERER"];

$browser = $_SERVER["HTTP_USER_AGENT"];

$file = fopen("log.html",  "a");  

$time = date("H:i dS F");

fwrite( $file, "<b>Time:</b> $time<br>" );

if( $address != null)

{

  fwrite( $file, "<b>IP Address:</b> $address <br>");

}  

if( $referer != null)

{

  fwrite( $file, "<b>Referer:</b> $referer<br>");  

}

fwrite( $file, "<b>Browser:</b> $browser<br/><hr>");  

fclose($file);

?>

当访问IP.PHP的时候会在当前目录生成一个LOG.HTML的文件，在浏览器即可查询
