Hi all, Can anyone think of a more elegant way of achieving the following? <?php $flags = array(); if ($allow_fraction) { 
    $flags[] = FILTER_FLAG_ALLOW_FRACTION;
} if ($allow_thousand) { 
    $flags[] = FILTER_FLAG_ALLOW_THOUSAND;
} if ($allow_scientific) { 
    $flags[] = FILTER_FLAG_ALLOW_SCIENTIFIC;
} if (count($flags) > 0) {
$tmp = FALSE; foreach ($flags as $flag) { 
        $tmp = $tmp | $flag;
} $filter['flags'] = $tmp; Nice one, thank you. Same amount of code but avoids the eval() which is all I wanted. Cheers, Rich 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?
