#98 value of a variable can't be '0'

[Mickael Bailly]

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.
