* You can use this on a single page or in a global header for site-wide
* use. You can also add a condition to isolate a page or a whole
* directory, depending on your needs. To use it on a whole site (as
* shown in this example), just paste the script below, above the global
* head or above the head of each page.
*
* Assuming a global head, you can also use this script to block page or
* directory access by using a condition like this:
*
* REF: http://mikecherim.com/experiments/php_directory_finder.php
*
* EXAMPLE URI: /experiments/php_maintenance_block.php
* Add this:
*    $path_parts = explode('/', $_SERVER['REQUEST_URI']);
*
* DIRECTORY BLOCK:
*    $path_part = $path_parts[1];
*    if($path_part == "experiments") {
*       // Add script below here to block access to matching directory
*    }
*
* PAGE BLOCK:
*    $path_part = $path_parts[2];
*    if($path_part == "php_maintenance_block.php") {
*       // Add script below here to block access to matching page
*    }
*
* NOTE: Do NOT change the formatting in STEP 1 below.
