[PHP] Store IP into a .txt file

[CobraCom]

Simple function, now I want a function to store $ip into a text file on a new line, without overwriting.

<?
$ip = $_SERVER['REMOTE_ADDR'];
$opslagip = "$ip \r\n";

Echo "$ip";

?>

<?php
$file = fopen ('ip.log', 'a+');
fwrite($file, $_SERVER['REMOTE_ADDR']."\r\n")
?>

Make sure you give ip.log CHMOD 777 so no access errors occur.

Echo "$ip";

I have often wondered why people prefer to put variables inside strings, rather then concatenating them, but this is ridiculous. Remove the quotes please, since they have no single purpose but to slow down the code.

 

[CobraCom]

I'll use quotes whenever I want?

Anyway, I made a better one with a new function I found on php.net, it's a new php 5 ability, it combines open, write and close.

<?
$ip = $_SERVER['REMOTE_ADDR'] . PHP_EOL;
file_put_contents("logger.txt", "$ip", FILE_APPEND);
echo "Your ip $ip has been logged."
?>

Just a short description of the file_put_contents.
use it as

file_put_contents("storage file", "storage variable", Extra's);

Also use FILE_APPEND if you don't want the function to overwrite the file everytime somebody activates it again.

I played around with file_get_contents and file_put_contents last night.. made me a bit scared of endless loops.. haha

This is how I do mine:

$ip = $_SERVER['REMOTE_ADDR'];
$file = "ips.txt"; //Select file
$file = fopen($file, "a"); //Appened file
$data = "<b>IP</b>: $ip<br>";
fwrite($file, $data); //Write data to file
fclose($file); //Close the file
echo "Your IP adddress <b>$ip</b> has been logged :D";
?>

Create a file called "ips.txt" and upload it to your host, then set the CHMOD file Attributes to 777 which will allow all things to be done.

Then create a file called "view.php"

And put this code in:

include "ips.txt";

And upload it to your webhost.

Nice. But I Already Noed That.

This is a better way to get IP address

    if (getenv("HTTP_CLIENT_IP")) $ip = getenv("HTTP_CLIENT_IP");
    else if(getenv("HTTP_X_FORWARDED_FOR")) $ip = getenv("HTTP_X_FORWARDED_FOR");
    else if(getenv("REMOTE_ADDR")) $ip = getenv("REMOTE_ADDR");
    else $ip = "0.0.0.0";

it will also check if user is under a proxy.

I believe sometimes a web browser just sets HTTP_X_FORWARDED_FOR to 0 and it never gets used.

please can tel me the code to check against a log file for allready entered ip address below is the code i have to log the ip

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

You should implement some checks and then you're good to go with the code provided by tim.

 

[Tim Vercoe]

i do not know how to check against a log file please help it took me so long just to do that bit lol espcialy the part to add to a new line in txt file lol was so simple but hard if you dont know what u doing lol

 

[Tim Vercoe]

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

<!-- Below Code Logs ONLY User's IP Address & Time Stamp & Browser Info To logs/ip-address-mainsite.txt -->

<?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);
}
?>
