Writing File -Help

[simon66]

Hi all,

 

This is my first php file im working on so bear with me.

 

What Im doing here is that I want my php script to add the users IP to a file without deleting the files inside of it and if the IP is already in the file then it wont add it

 

This is what I have to far

 

<?php
$ip = getenv("REMOTE_ADDR") ; 
$file = fopen("ip.txt", "w+");

fwrite($file, $ip);
fclose($file);
?>

 

the problem there is it will not add to the file, it will delete what ever is inside of the it and just add the new IP. Plus I still to add the search. If some one could help It would be amazing

 

Ill be looking around to see if I can do a search

Use the "a" mode to open the file for append.

<?php
$file = fopen("ip.txt", "a");
?>

It way also help to take the current contents of the file, store it as a temp variable, then rewrite the file, though this will get rather large if your going to be logging everyone who goes to your site.

How can I do that? Is it better if I store his IP in a Database?

To use a flat file you could something like this:

$ip = getenv("REMOTE_ADDR");
$lines=file("./ip.txt");

while (list($key,$value) = each($lines)) {

$value=trim($value);

if($value==$ip){$found=1; break;}
}
	if(!$found)
	{
	$write="$ip\n";
	file_put_contents("./ip.txt",$write,FILE_APPEND);
	}

 

What we are doing is putting the ip.txt file into an array then looping with a while/list/each. We use that cause as the file gets larger its a hit to use a foreach loop as a copy is used but a while/list/each goes line by line through the original array. We break if we find a match otherwise if we didnt find a match we append the IP to the file.
