php geo ip loc does not work - php

http://chir.ag/projects/geoiploc/
Hello, I am trying to set this up, but whenever I use include("geoiploc.php"); the page is blank and whenever I remove include("geoiploc.php"); I only see my IP address. I've uploaded geoiploc.php and index.php to a webhost that can run PHP.
If there is ANY other easier way to show country name by IP or any other way, which is it? Please I need this fast
So as I said, it only shows my IP whenever I remove include("geoiploc.php"); why?
You need this library: http://chir.ag/projects/geoiploc/autogen/geoiploc.tar.gz and this is the code to run the script:
include("geoiploc.php"); // Must include this
// ip must be of the form "192.168.1.100"
// you may load this from a database
$ip = $_SERVER["REMOTE_ADDR"];
echo "Your IP Address is: " . $ip . "<br />";
echo "Your Country is: ";
// returns country code by default
echo getCountryFromIP($ip);
echo "<br />\n";
// optionally, you can specify the return type
// type can be "code" (default), "abbr", "name"
echo "Your Country Code is: ";
echo getCountryFromIP($ip, "code");
echo "<br />\n";
// print country abbreviation - case insensitive
echo "Your Country Abbreviation is: ";
echo getCountryFromIP($ip, "AbBr");
echo "<br />\n";
// full name of country - spaces are trimmed
echo "Your Country Name is: ";
echo getCountryFromIP($ip, " NamE ");
echo "<br />\n";

You can use the free MaxMind Geo Lite. Download the files here: http://www.maxmind.com/download/geoip/api/php/php-latest.tar.gz
Then download the Geo Country database from here: http://dev.maxmind.com/geoip/legacy/geolite
You can now use it like this:
<?php
include("geoip.inc");
function ipAddress(){
if (!empty($_SERVER['HTTP_CLIENT_IP'])){ //check ip from share internet
$ip=$_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){ // proxy pass ip
$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
$ip=$_SERVER['REMOTE_ADDR'];
}
return $ip;
}
$gi = geoip_open("path/to/GeoIP.dat",GEOIP_STANDARD);
echo geoip_country_name_by_addr($gi, ipAddress());
// echo geoip_country_code_by_addr($gi, ipAddress()); <-- country code
geoip_close($gi);
?>
UPDATE: to get the user's city you should download the top link and look for the file called sample_city.php to see some example code. You'll need to download this file: http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz and place it in the same directory as your php file. A quick example would be:
<?php
include("geoipcity.inc");
function ipAddress(){
if (!empty($_SERVER['HTTP_CLIENT_IP'])){ //check ip from share internet
$ip=$_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])){ // proxy pass ip
$ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
$ip=$_SERVER['REMOTE_ADDR'];
}
return $ip;
}
$gi = geoip_open("GeoIPCity.dat",GEOIP_STANDARD);
$record = geoip_record_by_addr($gi,ipAddress());
print $record->country_code . " " . $record->country_code3 . " " . $record->country_name . "\n";
geoip_close($gi);
?>

why geoip not works for me

I am trying to working with geoip to display Ips and their Countries . I am trying to display this code but nothing comes up?
$country = geoip_country_name_by_name($ip);
You must have the GeoIP functions installed first. If they are installed, then it could be possible, that the IP you're providing to the function does not exist in the database.
Try this code:
<?php
$country = geoip_country_name_by_name($ip);
if ($country) {
echo 'This host is located in: ' . $country;
} else {
echo 'Cannot find the IP in the database.'
}

PHP Form processing algorithm

By way of partial explanation, my mind-set is strongly procedural, since I've been programming that way since the 60s
I'm working in PHP and trying to get my head around form handling starting with an interactive 404 error form. What I want in minimal pseudo-code is:
do {
OK = true;
display_form;
ask for optional name
ask for optional email address
ask for optional comments
on – submit{
sanitise input
validate input (which could be no input since all is optional)
if one or more inputs invalid set OK = false
}
} while (OK == false)
assemble email to webmaster using $_SERVER superglobals as well as input
send using mail function
Someone "helpfully" added curlies after the while AND at the end -- they really don't belong there -- the idea was that I wanted execution to "drop through" to those two statements only after the DO -- WHILE completed
The mail assembly could be in a separate file, or not
While this is a semi-specific problem, I'm working on the assumption that, if I can get this to work, then getting a database update working will be easier.
It seems to me that my whole conceptual algorithm is incorrect, and until I sort that I'm nowhere. I've been banging at this for a a couple of days – Google pointed at a number of semi-relevant answers here, so I'm giving it a go. The W3C examples clearly show the response code running even when there are problems with the input, which is not what I want.
The main switch you need to make here is probably the one to a request-response model of execution. You can't do a literal do..while, since you will need to send a response back to the client. The next iteration of that will be triggered by a new request to PHP, which begins again from the beginning and doesn't remember any previous state.
So, in pseudo code, it works like this:
if is POST request:
validate input, populate error variables
if input is valid:
send email with data
redirect to different page or display "thanks"
form start
for $field in fields:
output HTML for $field
maybe highlight if error
maybe set value to POSTed value to retain data
form end
So, upon the first page visit, it won't be a POST request and falls straight through to the form part. There won't be any errors or existing data, so the plain form will be output. When the form is submitted, the same code runs again and now enters the if is POST branch. If any values are invalid, it will fall through to the form again, which now can also output any error messages and existing submitted values. Only when all values are valid, will the server send an email and exit this "loop" by redirecting to another page, or maybe just outputting a "Thank you" note.
If you properly separate that into an MVC architecture, you'd have these components:
Model
data validation
email sending
View
outputs the form HTML
Controller
one for handling GET requests, just invoking the view
one for handling POST requests, essentially doing:
errors = model.validate(data)
if no errors:
model.send_email(data)
redirect()
else:
view.display_form(data, errors)
some form of router invoking the right controller based on the request URL and method
These could all be separate functions, or classes, or methods, or just files.
Below is the final code for the page. It's a basic 404 error page that may be of use to someone. And it should answer the requests that I supply the code that I was working with
It includes three files that I've not supplied:
top.php and footer.php and functions.php
top produces the HTML head statements including meta codes and also including top level banners and menu, as well as establishing the basic page format.
footer-- using the server superglobal just before the footer include, the page can provide a code update date for the page. And a consistent name and registration number for our organisation
functions.php supplies a bunch of reused functions. There are a couple of little (fairly obvious) functions in used in this code:
spacer outputs code to create an empty cell in a table.
spanCol creates a column spanning cell in a table, with the specified text and
specified tag open and close
The full page is at http://www.vfmc.org.au/notfound.php -- please don't send me too much junk email.
Code for the guts is here - I don't claim that it's brilliant, but it works thanks to help from here:

json_decode return null i guess

I try to run this on my server:
<?php
$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://ipinfo.io/{$ip}/json"));
echo $ip;
$city = $details -> city;
echo $city;
?>
But, this print ip only.
Maybe a server problem or configuration?
You need to code a bit more defensively, if that site has no data for the ip address you give it, then it wont return any city property
This is a little safer
$ip = $_SERVER['REMOTE_ADDR'];
$details = json_decode(file_get_contents("http://ipinfo.io/{$ip}/json"));
echo $ip . ' ';
if (isset($details->city)){
echo $details->city;
} else {
echo 'data not available';
}
Judging from what it returned for my IP Address, the details it provides are not very accurate anyway

PHP does not resolve .local dns names with gethostbyname

I have werid problem with name resolution. I am trying to connect to active directory server. I can successfully get the ldap server address from the SRV recodrs. Then I try to resolve the dns names to IP addresses and it fails:
<?php
echo 'example.com.:' . PHP_EOL;
echo gethostbyname('example.com.');
echo PHP_EOL;
echo 'dc1.veracomp.local.:' . PHP_EOL;
echo gethostbyname('dc1.my-company.local.');
echo PHP_EOL;
echo 'nslookup dc1.my-company.local.:' . PHP_EOL;
echo `nslookup dc1.my-company.local.`;
The example.com is resolved correctly, then the gethostbyname('dc1.my-company.local.') fails after a few seconds returning dc1.my-company.local. instead of the IP address. Still the same PHP script can call nslookup which correctly resolves the domain name...:
example.com.:
93.184.216.119
dc1.my-company.local.:
dc1.my-company.local.
nslookup dc1.my-company.local.:
Server: xxx.xxx.254.117
Address: xxx.xxx.254.117#53
Name: dc1.my-company.local
Address: 192.168.12.21
What is wrong here?
EDIT:
I am asking for name resolution beacuse the real problem i have is that I can connect to ldap://192.168.12.21 or to ldap://dc1.my-company.pl, but I cannot connect to ldap://dc1.my-company.local.
Unfortunatelly the SRV records for _ldap._tcp.my-company.pl returns only local addresses. I do not want to hardcode the .pl address. And I do not understand why I have to manually resolve the local addresses before passing them to Zend_Ldap as a host option.
You should avoid its use in production. DNS Resolution may take from 0.5 to 4 seconds, and during this time your script is NOT being executed.
I use this one; this will be faster and more efficient:
<?php
function getAddrByHost($hosts, $timeout = 3) {
$returnString = '';
foreach ($hosts as $host) {
$query = `nslookup -timeout=$timeout -retry=1 $host`;
if (preg_match('/\nAddress: (.*)\n/', $query, $matches))
$returnString .= trim($matches[1]) . '<br>';
$returnString .= $host . '<br>';
}
return $returnString;
}
$hostArray[] = 'www.example.com';
$hostArray[] = 'dc1.my-company.local';
$returnString = getAddrByHost($hostArray);
echo $returnString;
?>

PHP to return gethostbyname($lookup) value

I am using the code below (simplified version) to determine if my IPs are on a blacklist. I need to modify it to be able to determine if an IP is on a Whitelist. The function will require me to see a specific code returned.
127.0.0.1
127.0.0.2
127.0.0.3
127.0.0.4
127.0.0.5
How can this be adjusted to return the (code) output value when the script runs?
$host = '222.22.222.222';
$rbl = 'hostkarma.junkemailfilter.com';
$rev = array_reverse(explode('.', $host));
$lookup = implode('.', $rev) . '.' . $rbl;
if ($lookup != gethostbyname($lookup)) {
echo "ip: $host is listed in $rbl\n";
} else {
echo "ip: $host NOT listed in $rbl\n";
}
EDIT: Sorry guys, The function of the script above will return confirmation if the IP address is on the blacklist entered in $rlb. However, Hostkarma returns a code, one of the 127.0 codes shown above as each code indicates a different block status. I need to get the code. "echo $lookup;" just returns the reverse lookup, like this: 222.222.22.222.hostkarma.junkemailfilter.com
$lookup = implode('.', $rev) . '.' . $rbl;
$value = gethostbyname($lookup);
if ($lookup != $value){
echo "ip: $host is listed in $rbl\n";
echo "return value: $value\n";
}
else{
echo "ip: $host NOT listed in $rbl\n";
}
The 127.x.x.x code should be given to you as the value returned by gethostbyname.
Do you mean this?
echo $lookup;
