    (PHP 4 >= 4.3.0, PHP 5)
ob_get_clean -- 
     Get current buffer contents and delete current output buffer
    
Description
string 
ob_get_clean ( void )
     This will return the contents of the output buffer and end output
     buffering.  If output buffering isn't active then FALSE is returned.
     ob_get_clean() essentially executes both
     ob_get_contents() and
     ob_end_clean(). 
    
     
Example 1. A simple ob_get_clean() example 
<?php
  ob_start();
  echo "Hello World";
  $out = ob_get_clean(); $out = strtolower($out);
  var_dump($out); ?>
