Description
mixed 
highlight_file ( string filename [, bool return] )
     The highlight_file() function prints out a syntax
     highlighted version of the code contained in filename 
     using the colors defined in the built-in syntax highlighter for PHP.
    
     If the second parameter return is set to TRUE
     then highlight_file() will return the highlighted
     code as a string instead of printing it out. If the second parameter is
     not set to TRUE then highlight_file() will
     return TRUE on success, FALSE on failure.
    
Note: This function internally uses the
output buffering with this parameter so it can not be used inside
ob_start() callback function.
Note: 
      The return parameter became available in PHP 
      4.2.0.  Before this time it behaved like the default, which is FALSE

      Care should be taken when using the
      highlight_file() function to make sure that
      you do not inadvertently reveal sensitive information such as
      passwords or any other type of information that might create a
      potential security risk.

     Many servers are configured to automatically highlight files
     with a phps extension. For example,
     example.phps when viewed will show the
     syntax highlighted source of the file. To enable this, add this
     line to the httpd.conf:
    
| AddType application/x-httpd-php-source .phps |
