Nice one, thank you. Same amount of code but avoids the eval() which
is all I wanted.
Cheers,

Nice one, but you could also do it like this:
<?php
$filter['flags'] = FALSE;
if ($allow_fraction)
{
$filter['flags'] = $filter['flags'] | FILTER_FLAG_ALLOW_FRACTION;
}
if ($allow_thousand)
{
$filter['flags'] = $filter['flags'] | FILTER_FLAG_ALLOW_THOUSAND;
}
if ($allow_scientific)
{
$filter['flags'] = $filter['flags'] | FILTER_FLAG_ALLOW_SCIENTIFIC;
}
?>
Little bit simpler huh?
