Re: Full Range ?

Just to save a bit of code - is there an easier way without typing
out all the letters/numbers to do this?

foreach (range("A","Z") as $v){$variables[] = $v;}
foreach (range("a","z") as $v){$variables[] = $v;}
foreach (range("1","9") as $v){$variables[] = $v;}

Effectively making one array with all letters & numbers


Highly inefficient, but no typing of characters:

for ($i = 49; $i < 122; $i++) {
if ($i == 95) continue; // skip underscore
if (preg_match('/\w/', chr($i))) $variables[] = chr($i);
}

It would be better to array_merge the three ranges:

$variables = array_merge(range('A','Z'),range('a','z'),range(1,9));

Keeping the original format also allows you to add/delete included
characters in a more convenient way.

Won't a VAR_FILTER that'll do that? I'm using one for form validation.
