Sounds great, but as I am a total newbie, I think I'd go for the
array_merge() function though, it seems (from where I'm standing)
simpler than the recursive thing.
Would this be how it works?
$array1 = range(1,4);
$array2 = array(17,30);
$values = array_merge($array1,$array2);
if (in_array($a,$values){
echo "bingo";
}
PHP.net gave a caution about the range() function:
"In PHP versions 4.1.0 through 4.3.2, range() sees numeric strings as
strings and not integers. Instead, they will be used for character
sequences. For example, "4242" is treated as "4"."
Would that cause trouble if I'd have
$array = range(31,47);
?
