Answer 1

You can use FCPATH

application
purchase
purchase > dashboard
system
index.php

File

<?php 

if (file_exists(FCPATH . 'purchase/dashboard/filename.txt') {

   $handle = fopen(FCPATH . 'purchase/dashboard/filename.txt', "r");

   echo $handle;

}

?>

or

<?php 

if (file_exists('/purchase/dashboard/filename.txt') {

   $handle = fopen('/purchase/dashboard/filename.txt', "r");

   echo $handle;

}

?>

Codeigniter path functions definitions

EXT: The PHP file extension
FCPATH: Path to the front controller (this file) (root of CI)
SELF: The name of THIS file (index.php)
BASEPATH: Path to the system folder
APPPATH: The path to the "application" folder

Answer 2

Use absolute path. Try this,

<?php 

 $handle = fopen("/purchase/dashboard/filename.txt", "r");
 echo $handle;

?>
