Basic surfer information variables (from HTTP_SERVER_VARS)

Basic surfer information variables (from HTTP_SERVER_VARS)

Code:

<?php
$surfer_info[ip]=$HTTP_SERVER_VARS["REMOTE_ADDR"];
// $surfer_info[real_ip] will only contain something if the surfer used a transparent proxy
$surfer_info[real_ip]=$HTTP_SERVER_VARS["X_FORWARDED_FOR"];
$surfer_info[port]=$HTTP_SERVER_VARS["REMOTE_PORT"];
$surfer_info[browser_lang]=$HTTP_SERVER_VARS["HTTP_ACCEPT_LANGUAGE"];
$surfer_info[user_agent]=$HTTP_SERVER_VARS["HTTP_USER_AGENT"];
$surfer_info[request_path]=$HTTP_SERVER_VARS["PATH_INFO"];
$surfer_info[request_query]=$HTTP_SERVER_VARS["QUERY_STRING"];
$surfer_info[request_method]=$HTTP_SERVER_VARS["REQUEST_METHOD"];
$surfer_info[http_referrer]=$HTTP_SERVER_VARS["HTTP_REFERER"];
?>

I tried these codes in my site but to my surprise they didn't work. Plz help me.

It is just a row of variables, - it is up to you to decide how they are useful to your script and how to integrate them.

But if you want to see something happening any way, add

Code:

print_r($surfer_info);

to the bottom of the script (but before the closing ?>). Doing so will cause the script to show you what information the variables picked up.

Good idea.This is working very well for me.It was so simple.No real coding.Its really showing the information for my likings.

Very cool! One can also stick phpinfo() into the bottom of the file (temporarily, and only for one's self, preferably!) to see ALL the variables.

One question, what does the print_r() command do? I know the print() command but not that one.

print_r() visualizes the given array in a neat format which supports multiple dimensions.

Example output:

Code:

Array
(
[phpcentral_com] => Array
(
[users] => Array
(
[0] => Bill
[1] => Darkneboi
[2] => stalemate
[3] => penguinmama
[4] => etc
[5] => etc
)

[facts] => Array
(
[0] => PHPCentral.com saves cats from trees.
[1] => Chuck Norris approves of PHPCentral.com.
)

)

)

Welcome to the forum, by the way!

Oh, that's nifty! I'll have to fiddle with that print_r (and arrays!) a little more!

Wow, print_r is very neat! I can't believe I never knew about it.

Yeah, it is pretty cool, i have know PHP for a while but this is the first time i have encountered that command. I may try to use it more often.

the variable "$HTTP_SERVER_VARS" did not work for me. I had to use "$_SERVER"

Code:

<?php
$surfer_info[ip]=$_SERVER["REMOTE_ADDR"];
// $surfer_info[real_ip] will only contain something if the surfer used a transparent proxy
$surfer_info[real_ip]=$_SERVER["X_FORWARDED_FOR"];
$surfer_info[port]=$_SERVER["REMOTE_PORT"];
$surfer_info[browser_lang]=$_SERVER["HTTP_ACCEPT_LANGUAGE"];
$surfer_info[user_agent]=$_SERVER["HTTP_USER_AGENT"];
$surfer_info[request_path]=$_SERVER["PATH_INFO"];
$surfer_info[request_query]=$_SERVER["QUERY_STRING"];
$surfer_info[request_method]=$_SERVER["REQUEST_METHOD"];
$surfer_info[http_referrer]=$_SERVER["HTTP_REFERER"];
print_r($surfer_info);
?>
