有2种标准方法来使用 GeoIP


第一种方法:
先下载 GeoIP 数据文件

wget -c http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
gunzip GeoIP.dat.gz

接着下载 GeoIP 的 PHP 文件,保存为 geoip.php
http://geolite.maxmind.com/download/geoip/api/php/geoip.inc

好了,直接使用

php
 
     // 计时开始
     function  utime() {
         $time   =   explode (  "   " ,   microtime () );
         $usec   =  ( double ) $time [ 0 ];
         $sec   =  ( double ) $time [ 1 ];
         return   $usec   +   $sec ;
    }
     $startTimes   =  utime();
 
     //  include the php script
    // wget -c http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
    // gunzip GeoIP.dat.gz
     include ( " geoip.php " );
 
     //  open the geoip database
     $gi   =  geoip_open( " GeoIP.dat " , GEOIP_STANDARD);
 
     //  获取国家代码
     $country_code   =  geoip_country_code_by_addr( $gi ,   $_SERVER [ ' REMOTE_ADDR ' ]);
     echo   " Your country code is:  $country_code  
" ;
 
     //  获取国家名称
     $country_name   =  geoip_country_name_by_addr( $gi ,   $_SERVER [ ' REMOTE_ADDR ' ]);
     echo   " Your country name is:  $country_name  
" ;
 
     //  close the database
    geoip_close( $gi );
 
     // 运行结束时间
     $endTimes   =  utime();
     $runTimes   =   sprintf (  ' %0.4f ' ,  (  $endTimes   -   $startTimes  ) );
     echo   " Processed in  "   .   $runTimes   .   " second. " ;
?>

此方法使用二进制文件做为数据库,速度很快,不需要数据库。我试了执行时间是0.001,每秒完成1000次不成问题。


第二种方法:
把 GeoIP 安装成 PHP 扩展

yum install GeoIP GeoIP-data GeoIP-devel

下载 GeoIP 数据库

wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gzip -d GeoLiteCity.dat.gz
mv GeoLiteCity.dat /var/lib/GeoIP/GeoIPCity.dat

下载 GeoIP 的 PECL 扩展
下载地址 http://pecl.php.net/package/geoip

wget -c http://pecl.php.net/get/geoip-1.0.7.tgz
tar -zxvf geoip-1.0.7.tgz

安装 GeoIP 的 PECL 扩展

cd geoip-1.0.7
/usr/bin/phpize
./configure --with-php-config=/usr/bin/php-config --with-geoip
make
make install

在 php.ini 里加上

extension=geoip.so

接着重启一下 php 就行了

service httpd restart

现在,你可以使用 php 手册里的 GeoIP 部份函数了

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
