index_access.php

This is example for E-Market to use sequential file instead of database.

<?
// Read access permission data

	session_start();

	$filename = 'Database/EMarket/access.txt';

		$handle = fopen($filename, 'a+') ;

	   fclose($handle) ;
   }
   if (!$handle = fopen($filename, 'r')) {
		echo "Cannot open file ($filename)";
      exit;
   }
	$contents = fread($handle, filesize($filename));
	$a = split('~',$contents) ;

	fclose($handle);

// Data login
//
$username = $_POST["username"];
$password    = $_POST["password"];

// Verify, set environment and jump to it's main menu
