本文介绍如何使用PHP获取用户的真实ip，并且写入到txt文档 首先创建一个php文件，将下面代码放到PHP文件中<pre><code>&lt;?php
function getIp() {
if (getenv(&quot;HTTP_CLIENT_IP&quot;) &amp;&amp; strcasecmp(getenv(&quot;HTTP_CLIENT_IP&quot;), &quot;unknown&quot;))
$ip = getenv(&quot;HTTP_CLIENT_IP&quot;);
else
if (getenv(&quot;HTTP_X_FORWARDED_FOR&quot;) &amp;&amp; strcasecmp(getenv(&quot;HTTP_X_FORWARDED_FOR&quot;), &quot;unknown&quot;))
$ip = getenv(&quot;HTTP_X_FORWARDED_FOR&quot;);
else
if (getenv(&quot;REMOTE_ADDR&quot;) &amp;&amp; strcasecmp(getenv(&quot;REMOTE_ADDR&quot;), &quot;unknown&quot;))
$ip = getenv(&quot;REMOTE_ADDR&quot;);
 else
if (isset ($_SERVER['REMOTE_ADDR']) &amp;&amp; $_SERVER['REMOTE_ADDR'] &amp;&amp; strcasecmp($_SERVER['REMOTE_ADDR'], 
&quot;unknown&quot;))
$ip = $_SERVER['REMOTE_ADDR'];
 else
$ip = &quot;unknown&quot;;
return ($ip);
 }
 //输出ip
$myfile = fopen(&quot;ip.txt&quot;, &quot;a+&quot;) or die(&quot;Unable to open file!&quot;);
$txt = &quot;ip:&quot;;
fwrite($myfile, $txt); 
$txt = getIp();
fwrite($myfile, $txt); 
$txt = &quot;时间:&quot;;
fwrite($myfile, $txt); 
$txt = date('Y-m-d h:i:s', time());
fwrite($myfile, $txt); 
 $txt = &quot;\n&quot;;
fwrite($myfile, $txt);
fclose($myfile);
?&gt;
