Question

Where is the best place to create a class that contain all the application constant variables ?

is it :
– Bootstrap
– In the Application Common library

for example :
1- When i retrieve an image name from a database if this record doesnt have an image , i want to put a default value somewhere so i can use it in my models

** a constants that i use in all my application so if i change it , i dont want to go back to all in my code and change it everywhere

Answer 1

application.ini is the best place for example define some constant there

constants.PUBLIC_PATH =  APPLICATION_PATH "/../public/"
constants.THEME = blue

Then in your bootstrap do

protected function setConstants($constants)
{
    foreach($constants as $name => $value)
    {
         if(!defined($name))
            define($name, $value);
    }

}

ZF take ‘constants’ from config and call setConstants method in your bootstrap passing all lines prefixed by constants hence its an array .
