Custom Configuration File For Application

[eluser]saidbakr[/eluser]
Hello,

Thank you all for your valuable help, specially, n0xie. I found that the way I used to get the configuration value was wrong!

I used : $config['the_index_of_conf'] and hence the application returns error tell that variable - config- is not defined. However, from the user guide, it is stated that to call the config value, we have to use the item method of the configuration object some thing like:
$this->config->item('the_index_of_config') and this will return the config value.
