[PHP]blocking ip address from viewing site
« on: August 05, 2005, 09:33:18 pm »
<?php
include "nav.html";
print 
"<font color=\"white\">"$_SERVER['REMOTE_ADDR'] ."</font>";
if 
$_SERVER['REMOTE_ADDR'] = 127.0.0.1 Then {
echo 
"<meta http-equiv=\"refresh\" content=\"5; url=http://www.mysite.com/dir/noview.php\" />" }
?>


Why doesn't it work?

Edit: Returns this message
Parse error: parse error, unexpected T_VARIABLE, expecting '(' in /home/deadly7/public_html/ on line 15

That is line 15.

That's kind of eww-y code as it is. Here's a cleaned up version:


<?php

	
/**
	
* @return string
	
* @desc Searches for the enduser's IP-Address
	
*/
	
function 
get_ipaddr() {
	
	
	
	

	
	
if (
getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))
	
	
	
$ip getenv("HTTP_CLIENT_IP");
	
	
else if (
getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))
	
	
	
$ip getenv("HTTP_X_FORWARDED_FOR");
	
	
else if (
getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown"))
	
	
	
$ip getenv("REMOTE_ADDR");
	
	
else if (isset(
$_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))
	
	
	
$ip $_SERVER['REMOTE_ADDR'];
	
	
else
	
	
	
$ip "unknown";
	
	
	

	
	
	

	
	
return 
$ip;
	
}
	

	
$ip get_ipaddr();
	
$b_ip = array(
	
	
'127.0.0.1',
	
	
'64.233.167.99'
	
);
	

	
foreach(
$b_ip as $v) {
	
	

	
	
if(
$v == $ip)
	

	
	
	
header('location: www.google.com');
	
	

	
}
	

?>


By the way, the problem with your code is that 127.0.0.1 is a string. You didn't enclose it in quotes. Also -- PHP is pretty leniant on it's syntaxing, but I'm pretty sure it requires you to enclose if statements in parenthensies. Plus, you used "Then" and "{" looks like you were trying to merge VB6 and PHP. :)

Care to explain what that does? I've never used them before, and PHP.Net sucks at explaining things.

What the code does is it performs various checks to set an IP then uses a
for each to loop through the  array comparing it and forwarding them to google.com if they
match the list.

The exact methods he used can be found on php.net by searching: getenv();
One must ask oneself: "do I will trolling to become a universal law?" And then when one realizes "yes, I do will it to be such," one feels completely justified.

Because that's not valid PHP!

<?php
    
include("nav.html");
    echo 
"<font color=\"white\">" $_SERVER['REMOTE_ADDR'] . "</font>";
    if(
$_SERVER['REMOTE_ADDR'] = '127.0.0.1')
    {
        echo 
"<meta http-equiv=\"refresh\" content=\"5; url=http://www.mysite.com/dir/noview.php\" />";
    }
?>

* Sidoh gives a golfclap for warrior.
Very good! >_>

I already commented on why his code was invalid, rabbit. :P

Why do you weirdos use double-quotes when you're echo'ing html that uses double quotes for attributes? Make more work for yourself... freaks -_-

BTW, Rabbit. You missed something.

if($_SERVER['REMOTE_ADDR'] = '127.0.0.1')

Should be:

if($_SERVER['REMOTE_ADDR'] == '127.0.0.1')

Where'd you obtain your IP Address from?

www.whatismyip.com , here (I'm a mod and it shows my IP) , sb.net , and dota-allstars.com
Generally if 4/4 websites tell you that your ip address is what you thought it was, it's probably right.
No I don't run Firefox on any proxies or anything.

I've known people that think they can obtain their public IP address by using ipconfig:

Code: [Select]
Ethernet adapter Local Area Connection:

        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . : 10.0.0.4
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . : 10.0.0.2

Which is why I asked.

Anyway, use debugging. Make the routine echo the ip address it resolved and see if it matches with yours.

That's a strange "feature" of PHP I've encountered a few times myself. Try changing it to:

header('location: www.google.com'false);

Odd. I have yet to figure out why it does that on some servers. Probably something in php.ini. Just use that meta tag.

Code: [Select]
echo '<meta http-equiv="refresh" content="0; URL=www.google.com" />';
