you'll want to do a file_get_contents and then search through the entire file with strpos which is a lot less efficient than if you were to store the IP address in the database.

Why do you want to know if they've been there before?

Set a cookie if it's not too important... what if someone is at a university and has a shared IP address?

Setup a database table, add the email address and other details and do a SELECT query to see if that IP address, or email exists.

<?php
$iplogfile = '../logs/ip-address-contactform.txt';
$ipaddress = $_SERVER['REMOTE_ADDR'];

//load the file
$file = file_get_contents($iplogfile);

//check to see if the ipaddress is already in the file
if ( ! preg_match("/$ipaddress/", $file )) {
 //nope, log it!
  $webpage = $_SERVER['SCRIPT_NAME'];
  $timestamp = date('m/d/Y h:i:s');
  $browser = $_SERVER['HTTP_USER_AGENT'];
  $fp = fopen($iplogfile, 'a+');
  chmod($iplogfile, 0777);
  fwrite($fp, '['.$timestamp.']: '.$ipaddress.' '.$browser. "\r\n");
  fclose($fp);
}
?>

I don't know what the path to the file is. I used what you wrote. Try using a full path

tvercoe · March 6, 2015

i know i have change order of code around maybe but the coding seems right-ish

<!DOCTYPE html>

<html>

<head>

<?php

$iplogfile = 'logs/ip-address-mainsite.txt';

$ipaddress = $_SERVER['REMOTE_ADDR'];

$webpage = $_SERVER['SCRIPT_NAME'];

$timestamp = date('d/m/Y h:i:s');

$browser = $_SERVER['HTTP_USER_AGENT'];

$fp = fopen($iplogfile, 'a+');

chmod($iplogfile, 0777);

fwrite($fp, '['.$timestamp.']: '.$ipaddress.' '.$browser. "\r\n");

fclose($fp);

$iplogfile = '../logs/ip-address-contactform.txt';

$ipaddress = $_SERVER['REMOTE_ADDR'];

//load the file

$file = file_get_contents($iplogfile);

//check to see if the ipaddress is already in the file

if ( ! preg_match("/$ipaddress/", $file )) {

//nope, log it!

$webpage = $_SERVER['SCRIPT_NAME'];

$timestamp = date('d/m/Y h:i:s');

$browser = $_SERVER['HTTP_USER_AGENT'];

$fp = fopen($iplogfile, 'a+');

chmod($iplogfile, 0777);

fwrite($fp, '['.$timestamp.']: '.$ipaddress.' '.$browser. "\r\n");

fclose($fp);

}

?>

Yeah, you can't do a chmod() on a URL. It has to be a filepath.

tvercoe · March 6, 2015

this is what i ended up using as dont know what code is to chmod so have to manually make file ip-address-mainsite.txt and its chmod is 0777 it works mint thank you heaps

<?php

$iplogfile = 'logs/ip-address-mainsite.txt';

$ipaddress = $_SERVER['REMOTE_ADDR'];

//load the file

$file = file_get_contents($iplogfile);

//check to see if the ipaddress is already in the file

if ( ! preg_match("/$ipaddress/", $file )) {

//nope, log it!

$webpage = $_SERVER['SCRIPT_NAME'];

$timestamp = date('d/m/Y h:i:s');

$browser = $_SERVER['HTTP_USER_AGENT'];

$fp = fopen($iplogfile, 'a+');

fwrite($fp, '['.$timestamp.']: '.$ipaddress.' '.$browser. "\r\n");

fclose($fp);

}

?>
