dans un log.txt : reduire IP à deux octets selon recomm CNIL

[bird]

bonjour,
mon log (base moteur lionwiki) est créé par les lignes:

// -------------------------------------------------------------
// idem (selon méthode Chuwiki 3, page ip_log historique version 2006-06-06)
$time = date("Y-m-d H:i"); // repris de 2ème méthode ip_log de chuwiki
$ip = $_SERVER["REMOTE_ADDR"];
$page = $_SERVER['REQUEST_URI'];
$browser = $_SERVER['HTTP_USER_AGENT'];
$fp = fopen("./var/log/log.txt", "a");
fwrite($fp, "$time $ip $page $browser
");
fclose($fp);
//-------------------------------------------------------------

comment réduire l'ip nnnn.mmm.oooo.pppp à nnnn.mmm ?

merci

Une façon de faire serait ...

$ip = explode(".",$_SERVER["REMOTE_ADDR"]);

// par exemple
$ip = '10.192.0.34';
var_dump( preg_replace( '/(\.\d+){2}$/', '', $ip ) ); // '10.192'

// ou bien
$ip = '10.192.0.34';
var_dump( strtok( $ip, '.' ) . '.' . strtok( '.' ) ); // '10.192'

The log file created by this code will be unreadable and hardly parseable
because it will have only one long line: the trailing newline of each entry
is missing – fwrite() does not write it by default.

As for the rest, I recommend to use braces, concatenation, or (v)sprintf()
to avoid ambiguities –

fwrite($fp, "{$time} {$ip[0]}.{$ip[1]} {$page} {$browser}\n");

or

fwrite($fp, $time . ' ' . $ip[0] . '.' . $ip[1] . ' ' . $page
. ' ' . $browser . "\n");

or

fwrite($fp,
vsprintf("{$time} %s.%s {$page} {$browser}\n",
array_slice(explode('.', $_SERVER['REMOTE_ADDR']), 0, 2)));

or

fwrite($fp,
sprintf("%s %s.%s %s %s\n", $time, $ip[0], $ip[1], $page, $browser));

(in this simple case I would probably use braces, if only for “$ip[0]” and
“$ip[1]” to make clear that there is no concatenation. But note that Web
servers already can write such log files in a non-blocking fashion; there is
hardly a need to reinvent the wheel in a worse way) – …

… and, although and because this is an international newsgroup, to post here
in English only (in order to reach the widest possible audience), and to
post in French to <news:fr.comp.lang.php> instead.

Very nice, thank you.

There is a
");
just under

fwrite($fp, "$time $ip[0].$ip[1] $page $browser");

it seems to be a correct "newline" regarding results :

2015-03-29 03:35 ip.ip.ip.ip / Mozilla/5.0 (iPhone... etc
2015-03-29 03:35 ip.ip.ip.ip /index.php?page=Accueil Mozilla/5.0 ... etc

but now I have
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE,
expecting T_STRING or T_VARIABLE or T_NUM_STRING in
/..../lionwiki/index.php on line 50

line 50:$self = basename($_SERVER['SCRIPT_NAME']);

.htaccess as "php 1"

Are you saying the code is actually

fwrite($fp, "$time $ip[0].$ip[1] $page $browser
");

? If so, you need to post it EXACTLY AS WRITTEN. White space in
strings is important!

If not, then you must have another fwrite which adds a newline character
further down your code.

As for this problem - it is almost assuredly mismatched single quotes
higher up in our code.

This is where a syntactically intelligent editor comes in handy - you
can easily find things like this.

If so …

… this would not be possible because a standalone “")” is a syntax error.
Are you sure those lines are not from a previous run?

Assuming that “line 50:” is not in the original code, there is no syntax
error on this line. The reason for the problem must be before that line.

Impossible to say what you did wrong if you do not post the offending code
*verbatim* (indentation preserved, no prefixes or suffixes added) trimmed
down to the relevant lines.

Please post using your real name.
