Question

<?php 
  echo '<b>Your ip has now been logged:</b> ';
  echo $_SERVER["REMOTE_ADDR"]; 
$myip = "144.141.53.98"; //so it does not log your IP and spam up the log file
 //echo ' Your ip: '; 

if ( isset($_SERVER["REMOTE_ADDR"]) )    { 
echo '' . $_SERVER["REMOTE_ADDR"] . ' '; 
//echo "You are using Localhost";
} else if ( isset($_SERVER["HTTP_X_FORWARDED_FOR"]) )    { 
  echo '' . $_SERVER["HTTP_X_FORWARDED_FOR"] . ' '; 
//echo "Your ip is forwarded";
} else if ( isset($_SERVER["HTTP_CLIENT_IP"]) )    { 
  echo '' . $_SERVER["HTTP_CLIENT_IP"] . ' '; 
//echo "You ip is not forwarded";
} 

$file = fopen("ips.txt", "a+");
fwrite($file,$_SERVER["REMOTE_ADDR" ]."\n");

?>

现在好了以下这行代码

$myip = "144.141.53.98"; //so it does not log your IP and spam up the log file

我希望如果一个ip已经记录在日志文件中，那么它将不会再次记录ip

请帮帮忙？

<?php

 echo '<b>Your ip has now been logged:</b> ';
  echo $_SERVER["REMOTE_ADDR"]; 
$myip = "144.141.53.98"; //so it does not log your IP and spam up the log file
 //echo ' Your ip: '; 
$ip = $_SERVER['REMOTE_ADDR'];

if ( isset($_SERVER["REMOTE_ADDR"]) )    { 
echo '' . $_SERVER["REMOTE_ADDR"] . ' '; 
//echo "You are using Localhost";
} else if ( isset($_SERVER["HTTP_X_FORWARDED_FOR"]) )    { 
  echo '' . $_SERVER["HTTP_X_FORWARDED_FOR"] . ' '; 
//echo "Your ip is forwarded";
} else if ( isset($_SERVER["HTTP_CLIENT_IP"]) )    { 
  echo '' . $_SERVER["HTTP_CLIENT_IP"] . ' '; 
//echo "You ip is not forwarded";
} 

$file = file_get_contents('ips.txt');

// No Duplicate IP Address's

if(strpos($file, $ip) !== false)
{

    die("<br><br>Your IP Address: ".$ip." has already been logged.");

}

//Write IP To file

$file = fopen("ips.txt", "a+");`enter code here`
fwrite($file,$_SERVER["REMOTE_ADDR" ]."\n");
fclose($file);

?>

PHP Ip跟踪脚本，带有$ fopen .txt文件，但只写一次ip
