gmp_and operation ???

[Priti Solanki]

Well i don't understand why you said it's non-gmp problem...!!  anywayz

following is the PHP code

$m_string='0010';
$c_string='0011';
$andresult=gmp_and($m_string,$c_string);
echo base_convert(8,10,2);
echo '<br> get resource type'.get_resource_type($andresult);
echo '<br/>Result: '. gmp_strval($andresult);

and i am using gmp_and NOT gmp_add....
this is not working this is sure... as i am running PHP 5.3.1 in which
gmp.dll is available ... and please also note that when i change

$m_string='1000';
$c_string='1000';

the output of gmpand() is correct !! this is what i am amazing at... that's
the reason i say i might be missing something....
