application/helpers/common_helper.php

here is my common_helper.php 

function reg_code()
{
    $CI =& get_instance();
    echo "in registration_code";
    $registration_code = get_reg_code();
    return $registration_code;
}

function check_code($registration_code)
{
    $CI =& get_instance();
    $sql = "SELECT * FROM membership WHERE reg_code = '$registration_code'";
    $query = $CI->db->query($sql);

    if($query->num_rows() > 0){
        return FALSE;
    }else{
        return TRUE;

    $alha_result = random_string('alpha',1);
    $numeric_result = random_string('numeric',3);
    $reg_code = $alha_result.$numeric_result;
    $reg_code = strtoupper($reg_code);

    //check if code exists
    if(check_code($reg_code)){
        return $reg_code;
    }else{

My Custom Helper -- (custom_helper.php)

<?php  

if(!function_exists('p'))
{
    function p($arr)
    {
      echo '<pre>'; 
      print_r($arr);
      echo '</pre>';
    die;
    }
}

?>

and then i have created i sample.php file in project root directory

sample.php --

<?php 

include('./application/helpers/custom_helper.php');
$arr = array('1','2','3','4');
p($arr);

?>

Output --

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
)

please use this way, it will work 100% and do not use below line in helper file using that we can access helper methods outside the application folder.

if ( ! defined('BASEPATH')) exit('No direct script access allowed');

You use $CI = & get_instance(); in your helper functions after this call there is main framework class object in that $CI variable, that's why when you use it in Controller everything work. But when you use it inside core php file, you don't initialize framework classes, so method call get_instance() fails and nothing work.
