Hello there, this is the code

PHP Code:

<?php

 $iplogfile = "log.txt";
 $fp = fopen($iplogfile, "a");

 if ($fp)
 {
  fputs($fp, $_SERVER["REMOTE_ADDR"]." \n");
  fclose($fp);
 }

?>

Can someone help me how i can make if the $_SERVER["REMOTE_ADDR"] is aready on log.txt to dont add again the ip on log.txt

Thanks

PHP Code:

$already_logged = false; //Flag to determine if record already in log

$iplogfile = "log.txt";

//Open log to search for remote address
$handle = fopen($iplogfile, "r");
if ($handle) {
    while (!feof($handle)) {
        $buffer = trim(fgets($handle, 4096));
        if ($buffer == $_SERVER["REMOTE_ADDR"]) {
          //Remote address found, so update flag and stop looping through file contents
          $already_logged = true;
          break;
        }
    }
    fclose($handle);
}

if (!$already_logged) {
  //Entry not in log, so add
  $fp = fopen($iplogfile, "a");

  if ($fp) {
    fwrite($fp, $_SERVER["REMOTE_ADDR"]." \n");
    fclose($fp);
  }
} 


But, I don't recommend that you use that. It'd be more efficient, requiring fewer file reads, to just add the record to the file and then clean up duplicates later -- perhaps using a session variable to track if it had already been added during that session.

$cmd = "grep '{$ip}' '{$logfile}' || echo '{$ip}' >> '{$logfile}'";
exec($cmd);

Use the powah of teh leenoox!!!!
