Use Live database on local Wordpress install.

db.php

// Use live database on local installation


<?php
// paste this in a (new) file, wp-content/db.php
add_filter ( 'pre_option_home', 'test_localhosts' );
add_filter ( 'pre_option_siteurl', 'test_localhosts' );

function test_localhosts( ) {
  if (strcasecmp($_SERVER['SERVER_NAME'], '.dev') != 0 || strcasecmp($_SERVER['SERVER_NAME'], 'localhost') != 0 ) {
      return "http://".$_SERVER['SERVER_NAME'];
   }
  else return false; // act as normal; will pull main site info from db
}

Add this (and modify as needed) to /wp-content.
