Summary: value of a variable can't be '0'

Initial Comment:
 I got a template variable FILE_NB which can be equal to the string 0 
.  
But template function evaluate 0 as null and so gives me an error:  
<b>Template Error:</b> loadfile: FILE_NB is not a valid handle.<br>  
  
Test with this script to see the problem:  
  
require 'template.inc';  
  
$t = new template('/tmp');  
//no matter what page.tpl contains   
$t->set_file('page','page.tpl');  
$t->set_var('FILE_NB','0');  
$t->parse('out',array('FILE_NB','page'));  
  
  
Suggested modification:  
  
on the first line of the loadfile function, replace the test:  
!empty($this->varvals[$handle])  
with  
strlen($this->varvals[$handle])

The error says that FILE_NB is not a valid handle. Try this
instead:

  $t->parse('out','page');

parse syntax:

  parse($target, $varname, $append = false)

where $varname is defined in set_file for your example as
'page'.

  set_file($varname, $filename = "")

See documentation:

http://www.sanisoft.com/phplib/manual/templateMethods.php#templateMethodsInt
   
0 is substitiuted into templates many many times.

hth,

Joe
