GeoIP Introduction:
What is GEPIP?
The so-called GeoIP, is through the visitor's IP, positioning his latitude and longitude, country, provinces and cities, and even the location of the street information. The technology is not a problem, the key is to have a precise database. With accurate data sources on the enjoy high earn a little money, but to develop a spirit of cooperation, collective contribution to the enjoyment is our pursuit.
How is GeoIP used?
First we need data information, so first get a free database: GeoIP.dat.gz, then extract: GeoIP.dat, then the data file on-demand operation, this example uses PHP.
GeoIP + PHP Usage
Method One:
Download GeoIP PHP file geoip.inc. Package download
Copy the Code code as follows:
Include ("geoip.inc.php");
Open Data File
$gi = Geoip_open ("GeoIP.dat", Geoip_standard);
Get Country Code
$country _code = geoip_country_code_by_addr ($gi, $_server[' remote_addr ']);
echo "Your Country code is: $country _code";
Get Country Name
$country _name = geoip_country_name_by_addr ($gi, $_server[' remote_addr ']);
echo "Your country name is: $country _name";
Close File
Geoip_close ($GI);
Note: If you test locally because $_server[' remote_addr ' and $_server[' REMOTE_ADDR '] may be 127.0.0.1, the output content is empty. Can bring in the IP test yourself
Method Two:
Installing GeoIP into PHP extensions
Yum Install GeoIP Geoip-data geoip-devel
Download GeoIP Database
wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
Gzip-d GeoLiteCity.dat.gz
MV Geolitecity.dat/var/lib/geoip/geoipcity.dat
Download GeoIP PECL Extension
Download Address Http://pecl.php.net/package/geoip
Wget-c http://pecl.php.net/get/geoip-1.0.7.tgz
