What do you mean by no-op? I'm no native speaker, please explain. And
already 0/1? 0/1 is an integer, not a boolean.

<?php
$row['test'] = 1; //so, integer 1, can be cast to true
$istrue = (bool)$row['test'];
echo '$row[test] can be cast to ';
echo ($row['test'])?'true':'false';
$string = "\n%s is %sa boolean";
printf($string,'$row[test]',($row['test']===true)? '' :'not ');
printf($string,'$istrue',($istrue===true)? '' :'not ');
?>

Grtz,
