Using the remap with parameters

Second are preferred as $params in _remap are an array. And if there are only one item in that array, it will convert it into a string.
With the first option you are going to get Array to String converting error.

Also it will allow you to pass more then one param into that function e.g. index($arg, $arg2). First option gives you the entire array in $arg, and ignores $arg2.

Here's an example I wrote to another forum member. If the first parameter matches a function it will call that, else it will pass it into index().
So http://localhost/create will go to create() and http://localhost/everything-else will go to index('everything-else').

PHP Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Products extends CI_Controller {

    public function index($category='all')
    {
        echo 'Category: ' . $category;
    }

    public function create()
    {
        echo 'The create() method is called...';
    }

    public function _remap($method, $params = array())
    {
        if (method_exists($this, $method)) {
            return call_user_func_array(array($this, $method), $params);
        } else {
            if( empty($params) ) { $params[] = $method; }
            return call_user_func_array(array($this, 'index'), $params);
        }
        show_404();
    }
} 


Thanks, I'll study this form.

Just to double check, even if I use the form $params = array() in the remap parameter list it will still try to convert the one entry array to a string?
