Php – Codeigniter relative path file

codeigniterPHP

I am new to codeigniter (and php in general) and I am following the tutorial to learn it.
Following this link : https://www.codeigniter.com/user_guide/tutorial/static_pages.html

in the controller it checks whether the a file exists using

 if ( ! file_exists('application/views/pages/'.$page.'.php'))

My question is: this script is running from application/controllers/pages.php so isn't the path given to file_exists relative to the current script ? that is it should point to application/controllers/application/views/pages/'.$page.'.php'.

However this is not the case and the path in fact checks files relative to the path root !
So is this php matter or codeigniter ?

Thanks.

All paths are relative to the entry script (likely index.php or whatever Codeigniter uses).

To get paths relative to the current script use the __FILE__ constant.

file_exists(dirname(__FILE__) . "/path/to/file.php");

Changing the memory_limit by ini_set('memory_limit', '-1'); is not a proper solution. Please don't do that.

Your PHP code may have a memory leak somewhere and you are telling the server to just use all the memory that it wants. You wouldn't have fixed the problem at all. If you monitor your server, you will see that it is now probably using up most of the RAM and even swapping to disk.

You should probably try to track down the offending code in your code and fix it.

Php – Codeigniter extends core class

I needed to add the following code to /application/config/config.php before I got the extenson of core classes working as described in the CI manual.

Code taken from here http://philsturgeon.co.uk/blog/2010/02/CodeIgniter-Base-Classes-Keeping-it-DRY

function __autoload($class)
{
    if(strpos($class, 'CI_') !== 0)
    {
        @include_once( APPPATH . 'core/'. $class . EXT );
    }
}
