Cannot redeclare geoip_country_code_by_name

Today I had this error on my Ubuntu Linux box

Fatal error: Cannot redeclare geoip_country_code_by_name()

The reason was that I have geoip extension enabled in my PHP configuration and also I used the geoip.inc file from maxmind.com.

The solution is very simple. Actually, there are two solutions:

First is to disable the geoip extension from your configuration. In /etc/php5/apache2/conf.d/geoip.ini comment the first line:

[sourcecode language=”bash”]
;extension=geoip.so
[/sourcecode]

The second solution: in your geoip.inc file, look for this code

[sourcecode language=”php”]
function geoip_country_code_by_name($gi, $name) {
…
}

function geoip_country_name_by_name($gi, $name) {
…
}
[/sourcecode]

and replace with

[sourcecode language=”php”]
if (!function_exists(‘geoip_country_code_by_name’)) {
function geoip_country_code_by_name($gi, $name) {
…
}
}

if (!function_exists(‘geoip_country_name_by_name’)) {
function geoip_country_name_by_name($gi, $name) {
…
}
}
[/sourcecode]

Public, Private, and Protected in PHP

or how to manage access to your classes.

In PHP there are three levels of access for properties and methods from within a class: public, private, and protected.

Public access is the default setting for method and for properties.

  • Public properties and methods can be accessed from any context.
  • Private methods and properties can ONLY be accessed from within the enclosing class. The subclasses have no access to them.
  • Protected methods and properties can be accessed from within the enclosing class and from subclasses.

According with Zend Coding Standards, variables that are declared with the “private” or “protected” modifier, the first character of the variable name must be a single underscore.

eg: private $_myVar;
